Build a bench of blocks? Attach bench to a studded wall? Google curbless shower & do some supportive research, Your contractor might be afraid to think outside his box.

I did not cut any joists in this bathroom. There is a transition from the master to the bathroom to allow me to do the sloping, add in floor heating and waterproofing.

Building a curbless shower is expensive - if you want to do it right.

With planning many kits or ready made pans can be made to reduce the costs.

We did not use any of those methods. Instead. Italian Marble. Glass Blocks. Heirloom towel warmers. Roburn medicine cabinets.

This master bathroom is the polar opposite of cheap and fast....

I help design barrier free shower and you can hire me for as little as 20 minutes. Many people on Houzz really like this service I offer. Check out my reviews for more info. Or head to http://no-curb.blogspot.ca and make a donation.
