Adding a bathroom to your finished basement is one of the most valuable upgrades you can make to your home. Whether the basement is used for entertaining, a guest space, a gym, or a playroom, a bathroom adds convenience and increases your home’s resale value.

Most basement bathrooms fall into two main categories:

• • Powder Room (toilet + vanity)
• • Full Bathroom (toilet + vanity + shower)

Below is a clean breakdown of both options, what’s included, and typical costs in South Jersey to add in a bathroom within a basement remodel

Basement Bathroom Cost Overview

Powder Room ($12,000 – $18,000)

• Toilet, vanity, lighting, exhaust fan, flooring, basic finishes

Full Bath – Fiberglass Shower ($20,000 – $25,000)

• All powder room items + fiberglass shower

Full Bath – Tiled Shower ($30,000 – $40,000+)

• All powder room items + custom tiled shower, waterproofing, glass

Powder Room (Half Bath)

Best for Basements Used As:

• Entertainment areas
• Bar or lounge spaces
• Media rooms
• Home gyms
• Kids’ hangout areas

Typical Cost: $12,000 – $18,000

Why It’s the Most Affordable Option:

• No shower = minimal waterproofing
• Smaller footprint
• Faster installation
• Fewer plumbing requirements

A powder room keeps guests from running upstairs and provides a big convenience boost without the cost of a full bathroom.

Full Bathroom (With Shower)

A full bathroom makes the basement feel like a true extension of the home. This is the best choice if you plan to host overnight guests or include a bedroom in the basement.

Option 1: Fiberglass Shower Insert= $20,000 – $25,000

Benefits:

• More budget-friendly
• Faster to install
• Low maintenance
• Great performance for long-term use

Option 2: Fully Tiled Shower=$30,000 – $40,000+

Why It Costs More:

• Tile installation
• Schluter waterproofing
• Optional niches or benches
• Decorative tiles and mosaics
• Custom glass door

A tiled shower gives the basement bathroom a “main floor” feel and offers the best look and resale appeal.

What Can Affect the Price?

✔ Plumbing Location or Septic

If existing plumbing can be tied into, costs stay lower. If new drains must be added, the concrete floor may need to be opened. If a septic is present and can handle the new bathroom.

✔ Sewage Ejector Pump

Most homes require a pump to move waste to the main sewer line.

✔ Ventilation

Basement bathrooms require a dedicated exhaust fan.

✔ Finish Selections

Tile style, vanity quality, glass doors, fixtures, and lighting all influence the final price.
