Turning your basement into a livable, functional space? Adding a bathroom is one of the smartest moves you can make—and we’re here to help you do it right. At Evergreen Remodelers, we specialize in designing and building basement bathrooms that are beautiful, fully functional, and built to code.

A basement bathroom isn’t just a luxury it’s a game-changer for everyday convenience. Whether you’re converting your basement into a guest suite, home office, entertainment zone, or rental unit, a well-designed bathroom adds value, comfort, and independence to the space. No more running upstairs mid-movie or sharing tight morning routines.

Why Remodel Your Basement Bathroom?

Basements offer excellent potential for adding a bathroom, whether for guest use, a rental unit, or your personal convenience. A remodeled basement bathroom provides functionality in an often-overlooked part of the home. Whether you need a compact powder room, a full bath, or a luxurious spa-like space, we can design and build the perfect solution. With proper planning and expert execution, a basement bathroom can dramatically improve the livability and value of your home.

What We Include In Basement Bathroom Remodeling Custom Layout Planning

We begin with a comprehensive assessment of your basement’s layout, plumbing accessibility, and ventilation options. Whether you’re converting part of a finished basement or starting from scratch, we’ll create a floor plan that fits your goals and adheres to local Bellevue building codes.

Bathroom Plumbing Installation

Basement plumbing can be complex due to gravity-based drainage issues. Our licensed plumbers install or reroute lines, build sump pump or sewage ejector systems if necessary, and ensure everything flows safely and efficiently.

Shower And Bathtub Installation

We offer a wide variety of space-efficient options including corner showers, alcove tubs, walk-in showers, and tub/shower combos. All waterproofed and tiled with premium materials suited for below-grade conditions.

Toilet Installation

We install high-efficiency, low-flush, or pressure-assisted toilets, including upflush and macerating models designed specifically for basement installations. These are ideal for homes where traditional plumbing isn’t accessible below the main sewer line.

Vanities And Storage

One of the primary considerations in accessible bathroom remodeling is ensuring that doorways are wide enough to accommodate wheelchairs, walkers, and other mobility devices. We can widen your bathroom doors and hallways to make it easier for individuals to move around freely and comfortably.

Flooring Solutions

We use waterproof flooring materials such as luxury vinyl planks (LVP), porcelain tile, and sealed concrete to withstand basement humidity and reduce the risk of mold or water damage. Heated flooring systems can also be installed for added comfort.

Lighting And Ventilation

Basement bathrooms often lack natural light, so we install recessed lighting, LED mirrors, and well-placed task lighting to brighten the space. Our team also ensures your bathroom is equipped with proper exhaust fans and ventilation systems to prevent condensation and mildew.

Finishing Touches

From towel bars to shower niches and sleek hardware, we add every detail needed to make your new bathroom functional, attractive, and cohesive with your basement’s style.

Benefits Of A Basement Bathroom Remodel Adds Functional Living Space A basement bathroom makes your lower level more livable, whether it’s used for a guest suite, home office, gym, or entertainment area. It adds convenience for both residents and visitors.

Increases Property Value Adding a bathroom—especially in a finished basement—can significantly boost your home’s resale value. It enhances appeal to buyers and adds value to square footage that may otherwise be underutilized.

Ideal for Guests or Rental Units If you’re creating a guest bedroom or converting your basement into a rental unit (ADU), a basement bathroom is essential. It provides privacy and independence for anyone staying in your home.
