Shower remodeling — find out why the last one failed first

Most showers get remodelled because something went wrong, not because the tile went out of fashion. If nobody establishes what failed and where the water went, the new shower is built on the same assumptions as the old one and fails the same way on a slightly later schedule.

In short

What is shower remodel?

A shower remodel rebuilds an existing shower — the enclosure, the pan or base, the wall surface and usually the valve. The important distinction is between a cosmetic refresh, where the concealed assembly is sound and only the surfaces change, and a full rebuild, where the pan and the waterproofing come out because something failed. Which one you are buying is settled by finding out where the water has been going, and that has to happen before anyone quotes a finish.

Triggers

Signs you need shower remodel

A stain, a bulge or a soft patch on the ceiling directly below the shower — the clearest possible signal that the assembly is losing water
Tiles that sound hollow when tapped, or grout that keeps cracking in the same place no matter how often it is repointed
Water pooling on the shower floor after the water is off, which means the fall is wrong rather than the drain being blocked
A persistent musty smell in the room that cleaning does not touch
Loose or springy floor at the edge of the shower, or skirting and door frames swelling near the wet wall
The base or tray has flexed, cracked, or has a repair kit patch on it already

The job

How shower remodel actually works

Find out where the water is going before you choose anything

The useful order is: check the visible joints and the door seal, then the drain assembly, then the pan itself. A shower can lose water through a failed drain connection, a cracked pan, a breached membrane, or simply through a gap in the enclosure that soaks the floor outside it. These have different repairs and very different prices.

Watch for: Being sold a full rebuild before anyone has isolated the source. It is sometimes the right answer, but it should be the conclusion of a diagnosis rather than the opening bid.
Open enough to see the extent of the damage

Once the surfaces are off, the framing, the subfloor around the drain and the wall cavity beside the shower can be inspected. Damage from a slow leak is usually wider than the visible stain, because water travels along framing before it appears anywhere.

Watch for: A crew closing the walls back up on damp or blackened timber. Everything wet has to dry or be replaced before anything new goes over it, and drying takes days that nobody wants to schedule.
Rebuild the pan or base, and test it

Either a new one-piece base is set and its outlet connected, or a new sloped bed is built and waterproofed on site. Either way the assembly should be water-tested before anything covers it. This is the point at which the previous failure gets designed out rather than repeated.

Watch for: No test at all. A water or flood test on a finished pan costs an afternoon of waiting and is the only chance anyone has to prove the assembly holds before it is sealed under tile.
Rework the valve and the fixtures while the wall is open

A shower rebuild is the cheapest moment in the life of the room to fit a pressure-balancing or thermostatic valve, add a handheld on a slide bar, move the head to a sensible height, or build in a niche. All of these are wall-open work and none of them are practical afterwards.

Watch for: A like-for-like valve swap simply because it is what was there. If scalding when a tap runs elsewhere in the house is a known annoyance, this is the one opportunity to solve it.
Wall surface — tile, panel or a moulded surround

Tile over a waterproofed backer is the traditional route and the most adaptable to an awkward space. Large-format panels and moulded surrounds are faster, grout-free, and easier to clean, at the cost of a manufactured appearance and less flexibility on dimensions.

Watch for: Panels installed over the old surface rather than a new substrate, in a shower that was remodelled because of a leak. Speed is a feature only when there is nothing underneath that needs looking at.
Enclosure, door and the water that escapes anyway

A door or screen has to actually contain the spray pattern of the head you have chosen. Where the head is aimed at the opening, or where a fixed panel is too short, water leaves the shower and gets into the floor at the threshold — a failure mode that has nothing to do with the waterproofing and is frequently misdiagnosed as one.

Watch for: A frameless screen chosen from a photograph without anyone checking where the head points. It is a common cause of a "leaking shower" in a shower that is not leaking.
Ventilation, because the room is part of the assembly

A shower rebuilt into a room that cannot clear its own moisture will grow the same mould on the new grout. This is the moment to confirm the exhaust fan works, actually pulls, and discharges outside the building rather than into a roof space.

Watch for: A fan that hums but does not move air, and ducting that terminates in the attic. Both are extremely common and both quietly undo the work you have just paid for.

Money

What does shower remodel cost?

Shower remodels commonly run between $4,000 and $18,000. A surface refresh over a sound assembly sits low in that range; a full rebuild with a site-built pan, repaired framing and new glass sits high. The extent of concealed damage, not the tile selection, is what moves the number.

Straight answer

When shower remodel is the wrong call

Everyone else ranking for this is paid when you say yes. Here's when you shouldn't.

Nobody has established why the old shower failed. Rebuilding over an undiagnosed leak is the single most expensive mistake available here, because the new work hides the evidence and you get to pay twice.
The complaint is actually the door or the screen. Water escaping past a bad seal or a badly aimed head wets the floor outside the shower and looks exactly like a leak. Replacing a seal or repositioning a head is a fraction of a remodel, and it fixes the real problem.
The grout is discoloured but sound. Grout can usually be cleaned, and in many cases raked out and replaced or recoloured, for a very small share of a rebuild. Do that first and see whether you still want the remodel.
The whole bathroom is coming out in the near future. Rebuilding the shower in isolation locks the layout, and doing the demolition and making-good twice costs more than doing the room once.
The damage extends beyond the bathroom and has not been dealt with. Where the ceiling below is affected, or the wall cavity beside the shower is wet, the repair is a building repair with a shower remodel inside it — and it needs to be scoped and dried in that order.
You are being quoted an install-over system for a shower with known water damage behind it. That method is legitimate on a sound substrate and only on a sound substrate. Here it means sealing the problem in.

Before you sign

What to check when hiring for shower remodel

Before you quote a rebuild, how will you establish where the water was going?

The question that separates a remodeller from someone selling a shower. A specific method — check the drain connection, test the pan, look at the enclosure — is a good sign. "They all fail eventually" is not.
What happens if the framing or the subfloor is wet when you open it?

Likely on any shower that leaked. Agree how it is priced and whether the job pauses for drying before you have a room with no shower in it.
Will the new pan be water-tested before you cover it?

The one chance to prove the assembly holds while fixing it is still cheap. Anyone who builds pans properly expects this question.
Are you replacing the valve, and what type?

Wall-open work. A pressure-balancing or thermostatic valve fitted now costs a fraction of fitting one later, and it solves the scalding problem permanently.
Where will the head point, and will the screen you are quoting contain it?

The most under-asked question in shower design. Water leaving the enclosure is a leak by any practical definition, and it is designed in or out at quoting stage.
Have you checked that the exhaust fan works and vents outside?

A new shower in a room that cannot dry out will look old quickly. It is a small job attached to a big one and it should not need asking for.
What is being reused, and what is being replaced?

Ask for the line to be drawn explicitly — substrate, drain assembly, valve, trap. "Refresh" and "rebuild" are used interchangeably in sales conversations and mean entirely different things on a quote.

FAQ

Shower Remodel — questions people ask

How do I know whether my shower is leaking or just wet outside?

A rough field test: stop using the shower for a couple of days and see whether the stain below dries and stays dry. Then run only the shower head with the door properly closed and watch. Then, separately, block the waste and stand water in the pan for a while without running the head. Each stage points somewhere different — a stain that appears only when the head runs suggests the enclosure or the wall; one that appears from standing water alone points at the pan or the drain connection. It is not conclusive, but it tells a plumber where to start and saves you paying for the search.

Can a shower pan be repaired instead of replaced?

Sometimes. A cracked acrylic or fibreglass base can be repaired, and repairs to visible cracks are routine. What cannot be reliably repaired is a breached waterproofing layer under a tiled pan, because the failure is not where the symptom is and you cannot inspect it without taking the pan apart. The honest test is whether anyone can show you the actual defect. If the answer is a guess, you are being asked to pay for a repair that may not address anything.

How long does a shower remodel take?

A panel or surround system over a sound substrate can be a couple of days. A tiled rebuild is typically one to two weeks of working time, because waterproofing and setting materials need to cure between stages. Add days if wet framing has to dry, and add weeks after tiling if you are having custom glass made, since it is measured only once the walls are finished.

Is it worth converting to a curbless shower during a remodel?

If the floor structure allows the recess, this is by far the cheapest moment to do it — the floor is open anyway. Curbless is easier to clean, makes a small bathroom look larger, and keeps working if anyone in the household has trouble stepping over things later. The constraint is depth: the shower floor still has to fall properly to the drain without a curb to contain it, and where that depth is not available a low threshold is the honest answer.

Why does my new grout keep going mouldy?

Usually ventilation rather than grout. A bathroom that cannot clear moisture holds it on every cool surface, and grout is porous enough to show it first. Check that the exhaust fan genuinely moves air, that it runs long enough after the shower rather than being switched off with the light, and that its duct terminates outside the building rather than in the roof space. Where the mould is confined to a corner joint that keeps cracking, the cause is different: that joint needs a flexible sealant rather than rigid grout.

Should I keep the shower in the same place?

Almost always, unless the layout is genuinely broken. Keeping the drain and the valve where they are avoids opening the floor structure and avoids the discovery process that comes with it. Moving a shower is not an upgrade to the same job; it is a different job with a plumbing project inside it, and it belongs in a whole-room remodel rather than a shower one.
