Basement Bathroom Buildout in Beachwood, OH

A full bathroom built from the concrete up in an unfinished Cleveland basement — core-drilled drains, moisture-resistant framing, a walk-in glass shower and code-compliant plumbing and venting — completed in 10 days for $10,000–$12,000.

‍

The Challenge

The client had an empty corner in an unfinished basement and wanted to convert it into a fully functional bathroom. The priorities were maximizing space, clean modern design, moisture protection, and adding property value with durable materials — including a walk-in shower and a light, cohesive color palette.

‍

What We Did

We built the bathroom from the concrete up:

• Demolition and framing — core-drilled the concrete floor for new toilet, shower, and vanity drains, then framed new walls with pressure-treated bottom plates and moisture-resistant insulation for long-term durability.
• Plumbing and electrical — new underground plumbing tied into the existing main drain with code-compliant venting; two GFCI outlets, a vanity light, recessed LED lighting, and a ceiling exhaust fan.
• Walls and flooring — moisture-resistant drywall painted soft beige to open up the space, with waterproof luxury vinyl plank in a light oak tone.
• Fixtures and layout — a 36" white shaker vanity with brushed-nickel faucet and mirror, plus a glass-door shower enclosure with integrated shelving and a rainfall shower head.
• Finishes — clean floor and ceiling trim, with exposed joists and ducts left as-is for a modern industrial basement look.

The Result

A stylish, well-lit full bathroom where there used to be dead space — moisture-protected, code-compliant, and a real boost to the home's value. Adding a bathroom is one of the highest-return moves in a lower level; we cover the wider numbers in our guide to basement finishing costs in Cleveland.

Frequently Asked Questions

How much does it cost to add a bathroom to a basement in Cleveland?

This basement bathroom came in at $10,000–$12,000, including core-drilling the concrete for drains, framing, plumbing, electrical, tile and fixtures. Cost depends mainly on how far the new drains sit from the existing main line. For whole-basement figures, see our basement finishing cost guide.

Can you add a bathroom to a basement with a concrete floor?

Yes. We core-drill the slab and run new underground plumbing tied into the existing main drain, with proper venting to meet code. If the main line sits higher than the new fixtures, an ejector pump handles it instead — we confirm which applies during the free estimate.

Do you need a permit for a basement bathroom in Ohio?

Yes — plumbing and electrical work both require permits and inspection, and moisture-resistant construction matters more below grade than anywhere else in the house. We pull the permits and manage the inspections as part of the job.

How long does a basement bathroom take to build?

This one took 10 days from core-drilling the slab to final fixtures. Most bathroom remodels are quoted at three to six weeks, so building one from bare concrete inside two weeks comes down to having plumbing, electrical and tile handled by the same crew instead of waiting on subcontractors. Timelines stretch if the plumbing has to travel further, or if the basement needs waterproofing first — which we always handle before framing, never after.
