Bathroom Remodeling
Master baths, guest baths, and powder rooms — from tile and fixture swaps to full gut remodels with new layouts.
Bathroom Remodeling in Los Angeles
Bathrooms are the second-highest ROI remodel in LA, but they're deceptively complex — waterproofing, drain slopes, vent stacks, tile layout, and fixture rough-in all have to be right or you're dealing with leaks and callbacks. Alto Builders handles the full build so nothing gets missed.
We do design-build or build-to-spec. For design-build, Lana creates 3D renderings in Chief Architect so you can see tile patterns, fixture placement, and vanity layout before demo. Every project is tracked in Buildertrend with daily photos, a shared schedule, and real-time budget updates. CSLB #1118841.
What We Build
- Master Bathroom Renovations — Full gut remodels with walk-in showers (curbless or curbed), freestanding soaking tubs, dual vanities with stone tops, heated tile floors, and recessed medicine cabinets. We handle waterproofing with Schluter or Laticrete systems.
- Guest & Hall Bath Updates — New vanity, toilet, tile floor, tub surround or shower tile, fixtures, lighting, and exhaust fan. These are the fastest bathroom remodels we do — typically 3–4 weeks.
- Shower & Tub Conversions — Tub-to-shower conversions with frameless glass enclosures, linear drains, and custom niches. Or add a freestanding tub where a shower stall used to be. We replumb as needed.
- Tile & Stone Work — Large-format porcelain, marble mosaics, natural stone slabs, and handmade zellige. We do full waterproofing, backer board, and precision layout before any tile goes up.
- Plumbing & Fixtures — Thermostatic shower valves, rain heads, handheld sprays, wall-mount faucets, undermount sinks, and water-efficient toilets. We work with any brand — Kohler, Brizo, Waterworks, California Faucets.
Our Process
-
Design Consultation We measure your existing bathroom, discuss what you want to change, and give you a ballpark. For design-build, you get 3D renderings with tile selections and fixture placement before we start.
-
Planning & Permits Tile and fixture selections, final drawings, and permit applications. If you're changing plumbing layout or adding electrical, permits are required.
-
Construction Demo, plumbing rough-in, waterproofing membrane, backer board, tile installation, vanity and mirror, fixtures, glass enclosure, paint, and final connections. Daily photo logs in Buildertrend.
-
Final Walkthrough We check every grout line, caulk joint, drain slope, and fixture operation. Punch list items get handled before you use the bathroom.
