The cost of remodeling a small half bathroom can range from $2,894 to $3,511. A medium-sized half bathroom will cost you between $4,628 and $5,617. For a large half bathroom, be prepared to spend about $9,025 to $10,953. The cost of a half bathroom can go as high as $25,000.

Half bath remodel

A full bathroom has all the main components such as a toilet, sink, tub and shower (or a tub-shower combo). It is usually situated adjacent to a master bedroom.
A powder room or a guest bath, on the other hand, generally has a toilet, a pedestal or vessel sink, and a mirror. There are no showers or tubs.
Some homeowners may add bathroom storage and a vanity. The largest part of the half bathroom addition cost is almost always plumbing.

There is a significant difference between the two types of bathroom based on their remodeling cost. Needless to say, a full bathroom will be a lot expensive as it requires additional bathroom components, and hence will have higher material as well as labor costs.
While a powder room remodel costs between $3,000 to $10,000, a full bathroom remodel costs about $5,000 to $15,000 or more.

Your complete powder room remodel cost takes into account a number of factors, including the total square footage, the scope of renovation, the type of fixtures, the materials and bathroom flooring you choose, your zip code, local labor costs, and finishing details.

Moreover, the cost of a powder room remodel depends on whether you are using existing floor space or are building onto the house. Where it will be located also matters: if it's close to existing plumbing, it will cost you less.

To get a general idea, check out the table below for an estimate of how the cost varies according to city and project size.

Most homeowners add a half bathroom or powder room to their home for the convenience it offers their guests (bonus: they don't have to use the master bathroom) and because is not as costly as installing a full bathroom.

It's also easier to carve out space for a half bathroom from your existing floor plan than a full bath.

Once you make the commitment to build a half bathroom, you need to know how much of an investment this home improvement will be.

A carefully planned remodeling project can greatly increase the value of your property in the home buyers' market.

The ROI on your home sale can be up to 70% of your total investment, as long as you do the right groundwork, and use the right methods and materials.

  • Utilize the space with the right half bath design and layout.
  • Get your construction, plumbing, electrical and lighting in place.

  • Install a corner sink (preferably a pedestal, vessel or trough sink).
  • Get a minimally sized vanity with rounded corners.
  • Consider extending the counter/storage over the toilet.
  • Save space by mounting the towel bar or other fitments on the door.
  • Work with expert bathroom contractors.
  • Be sure to get a written warranty or guarantee from them.
  • The contract should detail the complete schedule, deadlines for milestones and payment schedule.
  • Maintain the timeline for an easier, faster renovation job.
