Insulate Your Bathtub
I just finished a full DIY remodel and one of the best choices we made was to stuff rockwool in every nook and cranny possible around our tub. I've taken a two hour bath without adding hot water. I had to open the window because I was sweating.
I really can't believe how long water stays hot.
It's a 60" alcove Wyndham Grayley - acrylic and extra deep.
