Hi, we are renovating the family bathroom, it's a full bathroom with a shower and a back to wall bath. I'm wondering whether I should allocate money towards underfloor heating or if we opt for the back to wall spa bath instead of normal bath. It's the only bath in the house, the en-suite only has a shower. My husband and I like to bath together on the odd 'bath night' :) .We live in Auckland, NZ. We'll likely sell within the next 3 years to downsize to a smaller place for just us 2. I'd love to hear your thoughts.
