Basement Bathroom Remodeling in Grand Rapids, MI — Adding Real Value Below Grade
Grand Rapids Luxury Basements handles basement bathroom additions and remodels in Grand Rapids, MI as part of our exclusive focus on below-grade spaces. A basement bathroom is one of the highest-ROI improvements you can make to your home — it removes the need to go upstairs during workouts, movie nights, or overnight guests.
Below-grade plumbing requires specific expertise that general bathroom contractors often lack. We handle concrete core drilling, below-slab drain tie-ins, waterproofed tile systems, and proper ventilation — all within Michigan Building Code (MBC) and Michigan Residential Code (MRC) requirements.
"A well-placed basement bathroom turns an occasional-use space into a fully self-contained floor of your home. We design it to serve the basement's actual purpose — not as a utility afterthought."
What We Build
- Half baths — toilet and sink for quick access without full shower
- Three-quarter baths — toilet, sink, and walk-in shower
- Full baths — toilet, sink, and tub/shower combination
- Wet rooms — fully waterproofed open shower areas with linear drains
- ADA-accessible configurations — wider doorways, grab bars, roll-in showers
- Luxury upgrades — heated tile floors, steam showers, dual vanities
Our Basement Bathroom Process
Plumbing Assessment
We locate the main drain stack and assess proximity, slope, and depth for the new drain tie-in. This determines whether a standard gravity drain or an ejector pump system (Saniflo-style) is the right solution for your specific basement.
Concrete Core and Rough-In
We core the slab where needed, install all plumbing rough-in (drain lines, water supply, vent stack), and have the rough-in inspected before closing the floor. No guesswork — every connection is verified before concrete is patched.
Waterproofing and Tile
All wet areas receive proper waterproof membrane (Schluter Kerdi or equivalent) before tile. We install tile surrounds, shower pans, and floor tile with appropriate slope for drainage. No shortcuts on waterproofing below grade.
Fixtures and Finish
We install all fixtures, vanity, mirrors, lighting, and exhaust ventilation. The finished bathroom is inspected, tested for leaks, and walked through with you before sign-off.
