Increased STR profits by adding a bathroom?

[Troy Ritter]

I have a 3100 sq ft, 4-BR, 2.5 BA STR in Anchorage, AK. The home isn't renting as well as I'd like and I'm looking to make it more competitive. The max capacity is 12 and my average party size over the last 5 years is 8.2.

I’m thinking that the #1 thing I can do to make the home more attractive to larger groups would be to add a bathroom. My own experience of renting a 3 bathroom VR with my 8 ski buddies is that 8 people sharing even 3 bathrooms is difficult.

I have a bid to install a 3/4 bathroom for $8,000. I estimate this would allow me to increase the nightly rate by at least $30. This seems like a no-brainier but I'm wondering if anyone has added a bathroom to a STR or has thoughts on the ideal number of bathrooms in STRs.

Thanks!
