Average bathroom size with shower

When we sat down with a couple of interior designers to get some ideas for our master bathroom layout and the design of our kitchen, we learned a few things about ‘standard dimensions’ and residential building code requirements (including standard shower size) that are good to know when designing a new home.

Below are the residential code requirements which apply specifically to the bathroom — important bathroom dimensions & standard sizes you need to know!

Plus, I’ve found a number of great online tools for designing your own bathroom, and lots of other great tips & resources that will save you time and money when designing your brand new (or renovated) bathroom.

Standard Bathroom Sizes

When it comes time to decide what size bathroom you really need, consider the following standard bathroom dimensions:

• Full bathroomdimensions (w/tub & shower combo, toilet & sink): 5×8 feet
• Small bathroomdimensions (w/corner shower, toilet & sink): 6×6 feet
• Half bathroom
