How to Calculate Cost of Adding a Second Bathroom
It's cheaper to fit a second bathroom into existing space than build a bathroom addition
By Glyn Sheridan
Adding a second bathroom can increase your home's value and may attract buyers. The cost per square foot to build a bathroom is higher than the cost per square foot to construct a recreation room or a bedroom because the bathroom includes the cost of fixtures and new plumbing. You can calculate the cost of a second bathroom with help from building professionals.
- What You Need to Know
- You'll need a preliminary budget and to know the size and location of your new bathroom.
- You'll also need a price list for your bathroom fixtures and the cost of a building permit.
Consult a builder about the feasibility of adding a second bathroom. Discuss desirable locations. It will be less expensive to remodel your home to create a second bath than to build a bathroom addition.
Get estimates from plumbers for running water lines and a sewer drain to your second bathroom. Depending upon your plumbing layout, this cost can vary greatly. If the new bathroom is close to the first bathroom and its plumbing, the cost will be less than if the new bathroom is far away from existing plumbing.
Hire an architect. An architect will assess your home's structure and design a bathroom to suit your needs while protecting the integrity of your home. If you're converting existing space into a bathroom, you may save some money by working with a designer and a contractor to determine the best layout.
Solicit estimates from builders. Present each with an identical bidding packet that contains a copy of the architect's design and a detailed list of the work you want the builder to complete. If the builder does not subcontract the specialty work to an electrician and a heating and air conditioning professional, you will have to get estimates from them as well.
Add the costs for the bathroom fixtures. Include a tub or a shower, or both, single or double sink and vanity, commode and mirror or medicine cabinet. You'll also need a ceiling light, vented fan and light over the medicine cabinet. Add the cost of tub, shower and sink faucets and drains, toilet tissue holder and towel bars.
