Scope
What this checklist covers
The preparation ground these prompts walk through.
- Whether the bath still earns the space it occupies in this particular household
- How the shower is genuinely used, by whom, and for what
- Screens, doors and curtains, and where water goes when each is opened
- Getting in and out, including who already struggles and what they hold on to
- Control and outlet positions, and the supply questions that belong with a plumber
Audience
Who this checklist is for
- Owners deciding whether to keep a bath, replace it with a shower, or fit both
- Households where the shower performance has always been a source of complaint
- Anyone weighing enclosure and screen options before committing to one
- Owners planning for how the room will work as the household changes
Timing
When to use it
- Settling a household disagreement about keeping or removing the bath
- Recording how the current shower behaves before anyone proposes a replacement
- Deciding screen and door arrangements against how the room is actually used
- Preparing supply and performance questions for a qualified plumber
- Thinking ahead about entry, exit and provision that may be wanted later
Limits
When it is not sufficient
This is general planning preparation. These situations need a qualified professional, and often the relevant authority.
- Establishing what your water supply can deliver, which needs a qualified plumber who has seen it
- Deciding what support rails or seating any person requires, which needs suitable professional advice
- Any decision about how the wet area itself is constructed, which sits entirely with qualified trades
- Selecting products, since suitability depends on your room, your system and your household
The checklist
Work through the sections
Tick the boxes on paper or on screen — nothing is stored, so print the page if you want to keep your marks.
1.Whether the bath still earns its place
This is the decision that shapes everything else in the room, and it is usually made on sentiment. Gather the evidence first.
Note how often the bath has genuinely been used recently and by whom, rather than how often the household feels it is used.
The gap between remembered use and actual use is usually large, and it is the single most useful fact in this whole decision.
If children are the main reason for keeping the bath, consider how their use is likely to change and note what happens when it does.
A bath kept for small children often outlives their interest in it, which is worth acknowledging while the room is still on paper.
Note whether the bath is used for anything besides bathing, such as washing a pet, soaking laundry or filling containers.
These uses are real and rarely mentioned, and they sometimes justify keeping a bath that would otherwise be removed.
Note whether there is another bath elsewhere in the home, and whether anybody would actually walk to it to use it.
Having a bath somewhere else changes this decision entirely, provided the household would realistically use it.
Decide what the space would be used for if the bath were removed, and write that down rather than leaving it as more room.
A vague notion of more space often turns into an oversized shower and a room that gained nothing, so name the replacement use.
Consider whether a shower over the bath would actually satisfy the people who want each, or leave both groups mildly unhappy.
The combined arrangement is the usual compromise, and it works well in some households and pleases nobody in others.
2.How the shower is genuinely used
Showers are chosen from photographs and used by real people with wet hair. Describe the second situation.
Note how many people shower in this room, whether they overlap in the morning, and whether anyone waits for someone else to finish.
Patterns of use drive both the enclosure decision and the supply questions, and they are easy to describe accurately.
Note whether people take unhurried showers or brief ones, and whether hair washing happens here or elsewhere.
Hair washing needs more space, more water and somewhere to put bottles, and it changes what the enclosure has to accommodate.
Note the height of the tallest person who uses the shower, and whether they currently have to stoop under the outlet.
Outlet position is set once and lived with, and the tallest user is the one who notices whether it was considered.
Note whether anybody sits or would prefer to sit while showering, now or in the foreseeable future.
Seating changes the enclosure size and the wall behind it, and provision made now is far simpler than provision made later.
What seating or support any individual needs is a matter for suitable professional advice, not for a general planning checklist.
Consider whether a handheld outlet is wanted alongside a fixed one, and note who would use it and for what.
A handheld outlet is what makes rinsing the enclosure, washing a child and cleaning the tray practical, which is why it is so often missed.
Note whether anybody rinses or wipes the enclosure after use, and be honest about whether that habit would survive a new room.
Some arrangements depend on this habit and disappoint without it, so the honest answer should be given before choices are narrowed.
3.Screens, doors and where the drips land
The screen decides how much water stays in the enclosure and how much lands on your floor. Judge it by behaviour rather than appearance.
Consider whether the enclosure has a sliding door, a pivoting one or a fixed panel with an open entry, and note what each needs from the room.
A pivoting door needs clear space outside it, a sliding one does not, and a fixed panel accepts more water on the floor beyond.
Note where water runs when a door is opened, and whether it lands inside the enclosure, on the floor or on the item stored beside it.
Every enclosure sheds water when it opens, and knowing where that water goes influences both the door choice and what is placed nearby.
If a curtain is being considered, note whether the household would keep it clean and closed properly, and where its lower edge would sit.
Curtains work well for people who look after them and poorly for people who do not, and pretending otherwise leads to a wet floor.
Look at the current screen and note where water sits along its frame or seals, and how hard those places are to dry or clean.
Frames and seals collect water and are where enclosures start to look tired, so noticing them now informs the choice.
Note what an opening door would swing or slide towards, including the towel, the basin, the toilet and anyone standing there.
Enclosure doors are usually positioned by the fitter unless the owner has stated a preference, and the consequences are daily.
Ask how the glass and its frame are cleaned, and note whether anybody could reach every part of it without unusual effort.
An enclosure that is awkward to clean is not cleaned, and it becomes the part of a new bathroom that ages fastest.
4.Getting in and getting out
Entry and exit are where bathrooms become difficult as households change. Record what is already happening rather than what should happen.
Note whether anybody in the household already hesitates, holds on or asks for help when getting into the bath or shower.
Existing behaviour is genuine evidence, and it usually predicts what the room will need before anyone is ready to say so out loud.
Note what people actually hold onto now, whether that is a basin edge, a screen frame or a tap, and mention it to a professional.
People hold onto whatever is nearest, including things not intended for it, which points to where support might genuinely help.
Whether any support may be fixed, and where, is for a qualified professional to determine along with what the wall behind can carry.
Note how it feels to step over the bath edge for the least steady person in the household, and whether that is likely to change.
Stepping over a bath edge onto a wet surface is the movement most households eventually find difficult, and it deserves discussing early.
Note how the floor surface feels underfoot when wet, both inside the enclosure and immediately outside it, and record your impression.
What you notice underfoot is worth describing to a professional, though on its own it settles nothing about how the surface will behave.
Surface suitability in wet areas is a professional matter governed by manufacturer information and local requirements, not by how a sample feels in a showroom.
Consider what provision could be made now for supports or seating that might be wanted in future, and ask what that would involve.
Provision made while walls are open is straightforward, and it commits you to nothing except keeping the option available.
If anybody is helped in the shower or bath, note where the helper stands, what they hold and how much space that actually needs.
Assisted use needs room outside the enclosure as well as inside it, and it is nearly always left out of the brief.
5.Flow, temperature and what the system does
How a shower performs comes from the whole system rather than the fitting on the wall. Describe the behaviour and let a professional interpret it.
Describe how the current shower behaves in plain terms, including whether the flow feels strong, weak, uneven or noisy.
Plain description is exactly what a plumber wants, and it avoids the owner reaching a conclusion about the cause.
Note what happens to the shower when a tap is opened elsewhere in the home or an appliance draws water.
This behaviour tells a professional a great deal about the system, and it is something only the household can observe over time.
Note whether hot water ever runs short when several people bathe in succession, and how the household works around it.
Capacity affects which shower arrangements make sense, and the household experience of it is more useful than any assumption.
If you want a large overhead outlet, ask a qualified plumber what it needs from the system and whether your home provides it.
Large outlets are chosen from images and disappoint on systems that cannot serve them, which is avoidable by asking first.
What your water supply can deliver must be established by a qualified plumber who has examined the system, never assumed from a product description.
Note whether the temperature drifts during a shower, and mention any household member who is particularly sensitive to that.
Temperature steadiness is a system and control question together, and it belongs in the conversation before anything is chosen.
Check what information a qualified plumber needs about your system before they can answer your questions properly.
Turning up with the wrong information delays everything, and it is easily avoided by asking what is needed in advance.
6.Where the controls and outlets sit on the wall
These positions are set once and used every day. They are easy to discuss now and far harder to move once tiling has been completed.
Consider whether the control can be reached and turned on without standing under the outlet, and note who would object if it could not.
Stepping into cold water to reach a control is a familiar irritation that comes entirely from where the control was positioned.
Note the range of heights using the shower, and ask what outlet arrangement would work for the tallest and shortest of them.
A fixed outlet suits one height well and others less so, which is why the range matters more than any single figure.
Consider whether you want a fixed outlet, an adjustable rail or both, and note who would use each and for what.
Households often want both without realising they need to say so before the wall behind is finished.
If the shower is over the bath, note whether the control sits where somebody has to lean across the bath to reach it.
Leaning across a bath to reach a control is a routine awkwardness that follows directly from a position nobody questioned.
Note where the outlet would sit relative to the door or screen opening, and whether spray would head straight for it.
An outlet aimed at the opening sends water out of the enclosure every time it is used, whatever the screen is made of.
Ask which parts of the arrangement could be changed later without opening the wall, and which would be fixed permanently.
Knowing what is reversible helps you decide where to spend attention now and where a later change would remain possible.
7.Cleaning it and living with it afterwards
The version of this room that matters is the one a long way after completion. Choose with that version in mind.
Note how quickly water marks appear on the current glass and metal finishes, and ask what the options under consideration require.
Some finishes show every mark and some hide them, and knowing which you have chosen prevents an unpleasant discovery.
Note who cleans this part of the room, how willingly, and what they use, then weigh the options against that reality.
An enclosure chosen for a diligent cleaner and used by a reluctant one will not look the way it did in the showroom for long.
If a tray is being considered, note whether its surface is textured, and ask what collects in that texture and how it is cleaned.
Textured surfaces are chosen for grip and cleaned with difficulty, which is a genuine trade rather than a free improvement.
Ask how the bath panel is removed and what can be reached behind it, and note whether that access would still work once tiling is done.
Access behind a bath is usually needed at an inconvenient moment, and it is often reduced or lost during the finishing work.
Ask which sealed edges around the bath or enclosure you will be maintaining, and what to watch for as they age.
Sealed lines are consumable, and knowing which ones are yours makes the difference between a small task and a leak.
Ask whether the screen or enclosure could be replaced later without disturbing the surfaces around it, and record the answer.
Enclosures reach the end of their life sooner than tiling does, so knowing how they come out is worth establishing early.
Preparation
Documents and information to gather
Having these to hand usually makes the first conversation shorter and more useful.
- Your written note of how often the bath and shower have genuinely been used recently, and by whom
- Photographs of the current enclosure showing the screen, seals, tray and the floor immediately outside
- Notes describing how the shower behaves, including what happens when water is drawn elsewhere in the home
- Any paperwork you hold describing how hot water is produced and stored for this bathroom
- A note of the tallest and least steady people who use the shower, kept for the design discussion
- Product information for any enclosure, tray or outlet you are seriously considering
Records
Decisions to record before work begins
Write these down in your own words, with the date, so everyone is working from the same version.
- Whether the bath stays, goes, or is combined with the shower over it
- What the space would actually be used for if the bath were removed
- Whether the enclosure has a sliding door, a pivoting one or an open entry
- Whether a handheld outlet is wanted alongside any fixed one, and who would use it
- Whether provision should be made now for seating or supports wanted later
- Which household member holds the strongest view on this, and what would change their mind
Professional review
Questions to discuss with qualified professionals
Bring these to the relevant qualified professional, supplier or authority. Requirements vary by project and location.
- What does the outlet arrangement I like need from a water supply, and does this home provide it?
- What does the behaviour I have described about the current shower suggest to you?
- Where would you position the control so it can be reached without standing in the spray?
- If seating or a grab support were wanted here at some point, what would need preparing behind the tiling?
- Which parts of this arrangement could be altered later without opening the wall?
- How would you handle the floor surface immediately outside the enclosure?
- What information about my system do you need before you can answer these questions?
- If the screen or tray reached the end of its life, how would it come out without damaging the tiling?
Blind spots
Commonly overlooked items
- How often the bath has genuinely been used, as opposed to how often people think it has
- Water running off the door onto the floor every time the enclosure is opened
- The control positioned so somebody has to reach through the spray to start it
- What the tallest person in the household does when they stand under the outlet
- Room outside the enclosure for whoever helps a child or another adult
- Whether the handheld outlet that makes cleaning practical was ever asked for
- How the bath panel comes off once the tiling has been finished around it
What this checklist does not do
- This checklist helps you weigh a decision; it does not indicate which arrangement suits your home, your household or your water supply.
- Anything to do with supports, seating or steadiness needs advice from someone qualified to assess the person as well as the room.
- What your water supply can deliver must be established by a qualified plumber who has examined the system rather than inferred from a product description.
- Surface suitability in wet areas is a professional matter governed by manufacturer information and requirements that vary by location.
