Luxury Wet Rooms in Birmingham, MI
Transform Your Birmingham Bathroom with a Custom Wet Room
A wet room is a waterproofed bathroom with a seamless walk-in shower area. Wet room floors sit level with the rest of the floor. Without shower trays of standard baths, an open-plan layout creates a sense of luxury and accessibility for modern living and age-in-place needs.
Unlike traditional bathroom remodels, wet room installations require specialized design and construction expertise. At MainStreet Design Build, our in-house team of architects, interior designers, and skilled craftspeople works together to deliver wet rooms Birmingham homeowners can trust—custom-tailored to your lifestyle, accessibility needs, and design preferences.

Complete Wet Room Installations from Design to Delivery
MainStreet Design Build is Birmingham’s trusted choice for safe, stylish, and fully fitted wet rooms. Designed to be completely watertight, wet rooms offer several advantages over traditional bathrooms:
100% Waterproof
Wet rooms are completely sealed to prevent leaks and protect against water damage.
Modern and Stylish
Without the need for a bulky shower tray, wet rooms offer a more open layout and a sleek, contemporary look.
Accessible for the Whole Family
With a level, barrier-free design, wet rooms are easy to access for everyone—including those using mobility devices—no need to step over a raised shower tray.
Easy to Clean and Maintain
Wet rooms often include a simple glass screen to help contain water while maintaining distinct wet and dry zones. With fewer barriers and a streamlined layout, they’re much easier to clean than a traditional bathroom.
Adds Value to Your Home
The modern, luxurious space a wet room provides can increase your home’s value by 5%.
How We Design and Build Wet Rooms for Birmingham Homeowners

Phase 1 – Design
It all starts with your vision. Whether you’re looking to replace an outdated, hard-to-clean tub or need a more accessible shower for a family member using a mobility aid, we’re here to listen. Our team takes the time to understand your goals, then brings them to life with conceptual floor plans and detailed 3D renderings.

Once your design is finalized, you’ll meet with your dedicated interior designer, who will guide you through selecting every detail—from fixtures and finishes to flooring and lighting. Your project manager will then develop a detailed construction schedule, secure all necessary permits, and ensure everything is in place for a smooth and efficient installation.

As construction gets underway, your project manager ensures clear, proactive communication every step of the way. Because you’re an essential part of the process, you’ll receive regular updates and milestone check-ins, so you’re always informed about your project’s progress. Our expert in-house team handles every stage—from waterproofing to tiling—with precision and care.

To this day, anyone that visits the basement bar is in awe of the uniqueness and one-of-a-kind feel.

Frequently Asked Questions About Wet Rooms in Birmingham, MI

How Much Will My Wet Room Cost?
The cost of your wet room project will depend on the scope and specific design choices. To provide a personalized and accurate estimate, we begin with a signed Design Agreement, which allows us to assess your existing bathroom and develop conceptual floor plans with realistic budget projections.
Can Anyone Have a Wet Room?
Whether you’re remodeling an existing bathroom or building a room addition, a wet room can be a stylish and practical choice for any home. Their open design not only creates a sleek, modern look but also helps maximize available space—especially in smaller layouts.
It’s important to note that wet rooms require specialized construction, with a strong focus on waterproofing and drainage. This includes installing a sloped floor to direct water toward a central drain and applying a waterproof membrane across all walls and floors. In some cases, additional work—such as using a floor former—may be needed to ensure proper drainage and long-term durability.
Are Wet Rooms Really Waterproof?
Yes—when properly constructed, wet rooms are completely waterproof. Before any tile is installed, the entire space is sealed with a specialized waterproof membrane across floors and walls to prevent leaks and moisture damage. To ensure your wet room is truly watertight, it’s essential to work with an experienced team like MainStreet Design Build, who follow best practices in waterproofing and installation.
