How to clean and care for a walk-in shower
A groutless shower is easier to keep than a tiled one, which is most of why people choose it, and it still asks for a few habits and a short list of things never to do to it. This page is the list: what to clean the walls and the pan with, the caulk and the drain that are yours to keep up, how to keep the glass clear, and which of those things matter to the guarantee.

The daily habit that does most of the work
Rinse the walls down after the last shower of the day and run a squeegee over the glass, run the fan for twenty minutes or so, and leave the door or the curtain open so the shower dries. That is ten seconds of effort and it prevents most of what the rest of this page is about: soap film, hard-water scale and the mildew that grows on a joint that never gets a chance to dry.
What to clean with, and what never to use
A mild, non-abrasive cleaner and a soft cloth or sponge, on all six of the wall systems we install and on the pan. Nothing gritty: no scouring powders, no steel wool, no abrasive pads, because they scratch acrylic and dull solid surface and stone composite, and the damage does not polish out of a printed finish. Keep solvents such as acetone away from acrylic. Keep drain-opening chemicals out of the shower altogether. Where the maker of your wall system publishes a care sheet that is stricter than this, the sheet wins; it comes with the product warranty we pass through to you, and it is worth keeping with the other paperwork.
Bleach is the question people ask most. Diluted bleach is tolerated by some finishes and dulls or discolors others, and the damage does not show until it has happened. A mild non-abrasive cleaner does everything bleach would do to soap film and body oils, and mildew on a caulk joint is a sign the joint wants replacing rather than bleaching. If you use bleach at all, keep it to the glass and the drain grate, and rinse it off the walls promptly.
The seams and the caulk
The joints between panels and where the walls meet the pan are sealed, and that sealant is the maintenance item in a groutless shower. It is yours to keep up, the way grout resealing is in a tiled one. Look at it every few months and replace it when it has pulled away from the panel or the pan, cracked, or grown mildew that does not clean off. In a shower used every day that is usually a matter of a few years rather than months.
The job itself is small and worth doing properly: cut the old bead out completely rather than laying new over old, clean and dry the joint, run a fresh bead of mildew-resistant silicone, tool it smooth, and leave it to cure for a day before the shower is used. Water getting through a joint that was left to fail is a maintenance problem rather than a waterproofing failure, and the guarantee page says so in as many words. A joint you have kept up that still leaks is exactly the thing to report.
If you have tile
A tiled bathroom floor, or a custom tile shower, adds grout to the list. Grout is porous, it absorbs soap and body oils, and it wants sealing periodically, which is a bottle and an afternoon. What grout is not is waterproofing: the membrane behind the tile does that job, and a stained or cracked grout line is a cosmetic and maintenance matter rather than a leak. A panel system on the shower walls with tile on the bathroom floor, which is the most common combination we build, keeps the grout out of the wettest place.
Glass, tracks and doors
Squeegee the glass after each use. Clean it with a mild cleaner or diluted white vinegar, keeping the vinegar on the glass and off the wall panels. A sliding door has a bottom track that collects water and wants a wipe; a pivot door has a seal along its bottom edge that can be cleaned and, years later, replaced. A factory protective coating makes glass easier to keep clear but not maintenance-free. The doors and glass page covers the coatings and the low-iron glass that stays clearer at the edges.
The drain
Hair is the cause of nearly every slow drain in a new shower, and a hair catcher over the drain and a plastic hair-removal tool every month or two handle nearly all of it. Chemical drain openers are the thing to avoid: they are hard on the finish of the pan and on the seals in the drain assembly, and they rarely reach a hair clog anyway. A linear drain has a grate that lifts out for cleaning. A drain that stays slow after the hair is gone is a plumbing question rather than a shower one.
Hard water
Hard water leaves scale rather than damage: a cloudy film on glass, white crust around the shower head nozzles, and a dull look on walls that are never wiped. In a house with hard water the squeegee habit matters more, scale on glass comes off with diluted vinegar, and a shower head that sprays unevenly usually wants its rubber nozzles rubbed with a thumb rather than replacing. A water softener stops the problem at the source, and it is a plumbing decision rather than a shower one.
The bars, the seat and the walls
Wipe the grab bars and the fold-down seat with the rest of the shower and check now and then that they feel as solid as the day they went in. Do not hang anything from the seat. And nothing should be drilled or screwed through the walls by anyone but us, because a membrane is a continuous barrier and a screw through it is a hole in it; if you want a bar, a shelf or a hook later, ask us to add it. That is the single most common way a homeowner ends part of their own coverage without meaning to.
What matters to the guarantee, and what does not
Re-caulking and grout resealing are yours; a leak through the pan or the walls we built is ours, for as long as the original buyer owns and lives in the home. If you ever see water where it should not be, stop using the shower and tell us before anyone starts a repair, and within thirty days of noticing it, because damage that got worse while a known problem waited is not covered. The products themselves are cared for and warranted on their makers' terms. All of it is written out on the guarantee page.
Common questions
What should I use to clean groutless shower walls?
A mild, non-abrasive cleaner and a soft cloth or sponge, on every one of the six wall systems and on the pan. Nothing gritty: no scouring powders, no steel wool, no abrasive pads, because they scratch acrylic and dull solid surface and stone composite. Keep solvents such as acetone away from acrylic, and keep drain-opening chemicals out of the shower altogether. Where the maker of your wall system publishes a care sheet that is stricter than this, its sheet wins, and it comes with the product warranty we pass through to you.
How often does shower caulk need replacing?
Look at it every few months and replace it when it has pulled away from the panel or the pan, cracked, or grown mildew that does not clean off, which in a shower used every day is usually a matter of a few years rather than months. The job is to cut the old bead out completely, clean and dry the joint, run a fresh bead of mildew-resistant silicone, tool it smooth and leave it to cure for a day before the shower is used. Caulk is a maintenance item that is yours to keep up, and water getting through a joint that was left to fail is a maintenance problem rather than a waterproofing failure.
Can I use bleach in an acrylic or solid-surface shower?
Not as a habit, and not without reading the care sheet for your wall system first. Diluted bleach is tolerated by some finishes and dulls or discolors others, and the damage does not show until it has happened. For all six of the systems we install, a mild non-abrasive cleaner does everything bleach would do to soap film and body oils, and mildew on a caulk joint is a sign the joint wants replacing rather than bleaching. Keep bleach, if you use it at all, to the glass and the drain grate, and rinse it off the walls promptly.
Does hard water damage a new shower?
It leaves scale rather than damage: a cloudy film on glass, white crust around the shower head nozzles and a dull look on the walls if they are never wiped. In a house with hard water the squeegee habit matters more than anywhere else. Scale on glass comes off with diluted white vinegar, kept off the wall panels; a shower head that sprays unevenly usually wants its rubber nozzles rubbed with a thumb rather than replacing. A water softener stops the problem at the source, and it is a plumbing decision rather than a shower one.
Is re-caulking covered by the guarantee?
No. Re-caulking and grout resealing are routine maintenance and are yours to keep up, and surface water getting through an unmaintained caulk or grout joint is a maintenance item rather than a waterproofing failure. What the lifetime leak-free guarantee covers is the waterproofing assembly behind the surface: the pan, the walls and the sealed connections to the structure and the drain. If a joint you have kept up still leaks, that is exactly the thing to report, and the sooner the better, because damage that got worse while a known problem waited is not covered either.
How do I keep a shower drain clear without chemicals?
With a hair catcher over the drain and a plastic hair-removal tool every month or two, which between them handle nearly every slow drain in a new shower, because hair is nearly always the cause. Chemical drain openers are the thing to avoid: they are hard on the finish of the pan and on the seals in the drain assembly, and they rarely reach a hair clog anyway. A linear drain has a grate that lifts out for cleaning. A drain that stays slow after the hair is gone is a plumbing question, not a shower one.
