Five Signs Your Shower Is Leaking Behind the Tile

July 1, 2026

A leaking shower is the single most common problem we get called for in Lakewood, and it is also the sneakiest. Water gets past the tile, soaks into the framing, and does its damage for months or years before anything shows on the surface. By the time you can see it, the fix is bigger than it needed to be. Here are the five signs worth catching early.

1. Grout and Caulk You Keep Re-Running

If you have re-caulked the same corner three times and it keeps peeling or cracking, the problem is not the caulk. Constant movement usually means water has gotten behind the surface and the substrate is swelling and shrinking as it wets and dries. Fresh caulk on a wet wall just buys a few weeks.

2. Tiles That Sound Hollow

Tap across the shower wall with a knuckle. A solid, well-bonded tile gives a tight click. A hollow, drummy sound means the tile has lost its bond to whatever is behind it, often because that backer got wet and started to fail. Hollow tiles are a strong hint the waterproofing underneath was never there.

3. A Musty Smell That Will Not Leave

A bathroom that smells musty even after it is clean and dry usually has moisture trapped somewhere it should not be. Wet framing and backer board grow mildew inside the wall, and no amount of surface scrubbing reaches it. Trust your nose on this one.

4. A Soft or Springy Floor

Walk near the shower and the base of the toilet. If the floor flexes or feels spongy, water has likely reached the subfloor. That is past the cosmetic stage and into structural repair, so it is worth acting on quickly before it spreads to the joists.

5. Stains on the Ceiling Below

If the shower sits over a finished space, a brown ring or a bubbling paint patch on the ceiling below is a clear sign water is getting through. Do not repaint over it and hope. Find the source first.

What a Real Fix Looks Like

None of these problems get solved by regrouting. The only lasting repair is to open the shower, replace any damaged framing and backer, and rebuild with a bonded waterproofing membrane over cement board before the tile ever goes back on. If the tub is involved, this is also the natural moment to consider a tub-to-shower conversion while the wall is already open.

Rainemu provides bathroom remodeling in Lakewood, CA, from full bathroom remodels and walk-in curbless showers to tub-to-shower conversions, tile and waterproofing, vanity and countertop installation, and accessible aging-in-place builds. Most of the calls we get do not start with a wish list. They start with a problem: a shower that leaks behind the tile, a 1960s layout that wastes half the floor, grout that will not come clean, or a tub nobody in the house can safely step over anymore. We are the crew that opens the wall, finds the real cause, and rebuilds the room so the problem does not come back. Homeowners near Del Amo Blvd and up toward the 90713 blocks call us for exactly that.

The most common issue we see in Lakewood is water where it does not belong. A tile shower that was never waterproofed under the surface will wick moisture into the framing for years before a soft spot or a musty smell finally gives it away. We do not skin over that kind of damage. We strip the assembly back to studs, replace anything rotted, and rebuild with a bonded waterproofing membrane and cement backer board so the water stays in the drain. That single detail is the difference between a remodel that lasts twenty years and one that fails in three.

Layout is the second thing people want fixed. A lot of the mid-century homes off Woodruff Ave were built with a narrow single bath, a door that swings into the vanity, and a tub crammed under a small window. We can move a wall, swap the tub for a roomier walk-in shower, float a wider vanity, and add the exhaust fan the original room never had. When the bones allow it, a smarter footprint makes a 5 by 8 bath feel twice its size without adding a square foot.

Not sure whether your bathroom actually needs a remodel or just a cleanup? A few signs are hard to argue with: caulk you have re-run three times that keeps peeling, tiles that sound hollow when you tap them, a floor that flexes near the toilet, or a vanity top you can rock with one hand. Those point to problems under the surface, not on it. We come out, look at the whole room, and tell you straight whether it is a targeted fix or a full rebuild. The consultation is free, and there is never pressure to book on the spot.

What a Bathroom Remodel Costs in Lakewood

Bathroom pricing comes down to the size of the room, how much has to be torn out, and the materials you pick. A powder room refresh is one of the most budget-friendly projects, a mid-range full bath sits in the popular middle, and an upscale primary bath with layout changes runs higher. The ranges below are typical for the Lakewood area, and we put the firm number in writing after a free in-home consultation.

Bathroom Remodeling Questions, Answered

How much does a bathroom remodel cost in Lakewood?

It depends on size and scope. A powder room refresh runs roughly $2,000 to $6,000, a mid-range full bath falls between $10,000 and $25,000, and an upscale primary bath with layout changes can reach $80,000. We give a firm written quote after a free in-home consultation.

How do I know if my shower is leaking behind the tile?

Common signs are grout that keeps cracking, tiles that sound hollow when tapped, a musty smell, or a soft spot in the floor near the shower. Any of those means water is likely getting past the surface, and the fix is to rebuild the shower with a proper bonded waterproofing membrane.

How long does a full bathroom remodel take?

A standard full bath in a Lakewood home usually runs about two to three weeks from demolition to the final fixture, depending on tile work and any layout changes. We give you a schedule up front and keep the job moving so the room is not torn up longer than it needs to be.

Do I need a permit to remodel my bathroom?

If the work touches plumbing, electrical, or the layout, yes, and we pull it. Permitting protects you, keeps the GFCI protection and anti-scald valve requirements in check, and matters when you sell. A cosmetic swap of the same fixtures in place often does not need one.

Should I convert my tub to a walk-in shower?

If nobody uses the tub and stepping over the wall is getting harder, a tub-to-shower conversion is one of the best-value upgrades we do. It opens up the room and can be built low-threshold or fully curbless for easy access. If you have small kids or resale in mind, we may suggest keeping one tub in the house.

How do you make sure a new tile shower will not leak?

We build behind the tile, not just on it. That means cement backer board, a bonded waterproofing membrane set to ANSI A118.10, a properly sloped pan, and correct drain and P-trap connections. The tile is the last layer, and the waterproofing underneath it is what actually keeps the wall dry.

Can you make my bathroom accessible for aging in place?

Yes. We install grab bars on blocking rated for a 250 pound load, build a curbless roll-in shower, set a comfort-height toilet, and lay slip-resistant flooring, all planned to ICC A117.1 clearances. The goal is a bathroom that stays safe and usable for the long run without looking like a hospital room.
