Waterproofing done right. Finishes built for daily life.

Bathroom Renovations

Built To Last From Behind The Tile Out.
A beautiful bathroom starts long before the tile is installed. Built To Last Construction, Inc. approaches every bathroom renovation from the inside out, beginning with proper waterproofing, substrate preparation, and plumbing before moving on to tile, vanities, fixtures, and finish materials. The goal isn’t just a bathroom that looks beautiful on completion day, but one that performs reliably for years to come.
Bathrooms experience more moisture than almost any other room in a home, which means the work hidden behind the finished surfaces matters just as much as what you can see. That’s why we pay close attention to waterproofing systems, drainage, ventilation, and material compatibility before the first tile is ever installed. Taking the time to build the foundation correctly helps prevent leaks, mold, and costly repairs later.
Every project begins with a thorough evaluation of the existing bathroom. Whether you’re updating a guest bath, creating a spa-like primary suite, or remodeling as part of a whole home renovation, our process stays the same. We focus on thoughtful planning, quality craftsmanship, and building a bathroom that feels just as functional years from now as it does the day it’s completed.

What is included

We’ve completed bathroom renovations throughout Venice, Playa Vista, Culver City, Marina del Rey, and surrounding Westside communities, creating bathrooms that balance everyday comfort with lasting performance.
How We Work

A clear path from first call to final walkthrough.

01

Initial Site Assessment

We inspect the existing plumbing, framing, ventilation, and moisture conditions before recommending a renovation plan. Every decision starts with understanding what’s behind the finished surfaces.

02

Design And Material Selection

Layouts, fixtures, tile, cabinetry, and finish materials are selected and priced before demolition begins. Finalizing specifications early helps keep the project on schedule and minimizes unexpected changes.

03

Waterproofing And Installation

Waterproofing systems, substrate preparation, plumbing updates, and finish materials are installed in the proper sequence. Every layer is completed to manufacturer specifications before the next begins.

04

Final Inspection And Handoff

Tile, plumbing fixtures, glass, lighting, and finish details are inspected before the final walkthrough. We complete punch list items, verify everything is operating properly, and hand over a finished bathroom that’s ready to use.

Why BTL for Bathrooms

Waterproofing first. Finishes second. Every time.

Most bathroom renovations fail at the waterproofing stage, not the tile stage. BTL inverts the typical contractor priority: we spend more time and care on what you never see than on what you do. The finish reflects that.
Substrate done correctly
Mortar bed, waterproofing membrane, transition strips, and substrate preparation are completed before any tile is installed. This is where many bathroom failures begin, so we never rush the work behind the finished surfaces.
Every waterproofing system is installed according to manufacturer specifications and inspected before moving forward. Building from a solid foundation helps protect your bathroom from moisture problems for years to come.
Coastal humidity specifications
Westside homes by the ocean experience constant moisture, salt air, and changing temperatures. We recommend grout, sealants, and hardware that are selected to perform in these demanding conditions.
Choosing materials that fit the environment helps reduce maintenance and extends the life of your finishes. We focus on long-term durability, not simply what looks good on installation day.
No open-ended plumbing surprises
Existing plumbing is inspected and documented before pricing begins. If outdated piping, drain issues, or other hidden conditions are found, they’re addressed in the project scope before demolition starts.
That upfront planning helps prevent unexpected change orders and costly delays once construction is underway. Our goal is a renovation that stays predictable from start to finish.
Complete at handoff
Every fixture, shower enclosure, vanity, mirror, and hardware component is inspected before the project is considered complete. We don’t leave unfinished details for homeowners to chase down later.
Before the final walkthrough, we verify that everything is operating properly, complete any remaining punch list items, and ensure your new bathroom is ready to enjoy from day one.
What to Expect

A Bathroom Renovation Done Correctly Takes Planning. Here's How BTL Approaches Every Scope.

A successful bathroom renovation begins long before demolition. BTL starts every project with a detailed inspection of the existing plumbing, framing, ventilation, subfloor, and moisture conditions. Water damage, previous repairs, and hidden issues are documented before the scope is finalized so the renovation begins with a clear plan instead of assumptions.
Once the design is approved, materials, fixtures, and finish selections are finalized before construction begins. Tile, vanities, plumbing fixtures, lighting, and glass are coordinated in advance so lead times and scheduling stay on track. If your bathroom renovation is part of a whole home remodel, we coordinate every phase so the finishes flow naturally throughout the home.
Before any tile is installed, waterproofing systems, substrate preparation, and plumbing updates are completed in the proper sequence. We follow manufacturer installation requirements and proven building practices because the performance of a bathroom depends on the work hidden behind the finished surfaces as much as the finishes themselves.
Throughout construction, you’ll have a single point of contact and regular communication about progress, scheduling, and upcoming decisions. Before the final walkthrough, every fixture, shower enclosure, cabinet, mirror, and hardware component is inspected, punch list items are completed, and the space is cleaned so your bathroom is ready to enjoy from day one.
Common Questions

Answers before you ask.

If your question is not here, we are happy to talk it through on a call.
How long does a bathroom renovation take?
Most primary bathroom renovations are completed in about six to ten weeks once permits, materials, and final selections are confirmed. The timeline varies depending on the scope of work, custom finishes, and any hidden conditions discovered during demolition.
Before construction begins, we’ll provide a realistic schedule and keep you updated throughout the project so you always know what to expect as work progresses.
Do you handle custom tile work?
Yes. BTL regularly installs porcelain, natural stone, mosaic, and large-format tile for floors, showers, and feature walls. We can work with your preferred supplier, or we can recommend trusted products and vendors based on your project goals.
Proper layout, substrate preparation, and waterproofing are completed before installation so the finished tile performs just as well as it looks.
Do you work with my plumber or do you supply one?
BTL coordinates all licensed plumbing, electrical, and specialty trades required for your bathroom renovation. You won’t have to schedule separate contractors or manage multiple companies throughout the project.
Having one team coordinate the work helps keep the schedule organized, reduces delays, and ensures every phase is completed in the proper sequence.
