Bathroom Remodeling
Bathroom remodeling built on proper waterproofing — the difference between a bathroom that lasts 25 years and one that leaks in five. Serving LA and Ventura Counties.
Small room, high stakes
Everything that decides whether a bathroom lasts is buried behind the tile. The J Hammer builds bathrooms the right way — with a real waterproofing system behind every wet surface — so your remodel looks beautiful on day one and stays that way for decades.
Scope levels
- Refresh — new vanity, toilet, fixtures, tile floor, paint and lighting, layout unchanged.
- Full remodel — down to the studs: new shower or tub with proper waterproofing, wall and floor tile, vanity, and plumbing and electrical to code.
- Primary suite — expanded footprint, curbless shower, freestanding tub, custom stone and cabinetry.
The waterproofing that matters
Tile is not waterproof and grout is not waterproof — the bonded membrane system behind them is, and it is exactly where cheap bathroom remodels fail. A correct shower in 2026 means a waterproofing membrane over the pan and walls, flood-tested before a single tile goes on, with sloped pre-pans and sealed niches. It adds a day; skipping it eventually costs a subfloor and the ceiling below.
The details that age a bathroom well
- Ventilation sized to the room so paint does not peel and mirrors do not stay fogged.
- Cement board, not drywall, behind wet-area tile.
- Silicone at every plane change — grout cracks where walls meet; silicone flexes.
If two bathrooms share a wall or a plumbing stack, remodeling them together saves real money — one mobilization, one tile crew run, one inspection sequence.
