We’ve also had multiple >6ft 5” users comfortably fit and head dunk without their knees popping out or water spilling over the edge.

"Best part is that being 6’- 4” I STILL totally fit in the tub, all the way submerged up to my chin, without needing to do a yoga pose just to fit. I can comfortably sit, fully under the water, every time AND I can grab the top rails to pull myself up when getting out (unlike a normal tub)." - Ian Rice.
