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.

Serving Grand Rapids and Kent County

We serve Grand Rapids, MI and surrounding Kent County communities including Kentwood, Wyoming, Walker, Grandville, East Grand Rapids, Cascade, Caledonia, Rockford, Plainfield, and Ada.

Frequently Asked Questions

How much does a basement bathroom addition cost in Grand Rapids?

A basic 3-piece basement bathroom (toilet, sink, shower) typically ranges from $8,000 to $18,000 depending on plumbing location, tile selection, and fixture grade. Full bathroom remodels with custom tile and high-end fixtures may exceed this range.

Do I need to break the concrete floor to add a basement bathroom?

Usually yes — for a below-grade toilet, the drain line must tie into the main sewer below the slab. We core the concrete, install the rough-in, then patch and finish the floor seamlessly.

Do I need permits for a basement bathroom in Grand Rapids?

Yes. Plumbing and electrical work for a basement bathroom requires permits from the City of Grand Rapids Building Safety Division. We handle all filings and inspections on your behalf.

Can I add a full bathroom with tub or shower?

Yes. We install full bathroom configurations including walk-in showers, soaker tubs, double vanities, and full tile surrounds. We design the space to maximize function in the available footprint.

How long does a basement bathroom addition take?

Most basement bathroom additions take 2–4 weeks from permit approval to final inspection. Complex builds with custom tile or significant plumbing relocation may take 4–6 weeks.

What types of basement bathrooms do you build?

We build half baths (toilet + sink), three-quarter baths (toilet + sink + shower), and full baths (toilet + sink + tub/shower). Layout is designed to your basement's existing plumbing proximity and your usage needs.
