Basement 280 Gallon Build:

[Seth81]

True the shower doesn't have to be center to the shower especially with a tiled shower. But the slab has a hydronic radiant floor heating system, so there is no way I will be moving that drain!

Yeah maybe front access is all that's needed? Maybe also go to 90" so there is room on the sides so I can mount some power heads?

But if it was me I'd probably just make the tank 36" or even 30" deep to allow for the overflow, some plumbing and whatever else. Access from front is really for the best anyway. Every once in a while you'll need to scrap and clean near the seams of the glass, would be a nightmare from the back on that size of tank. Some stuff in this hobby is hard enough, doing it backwards doesn't seem like the smartest way to enjoy it.

Yeah for sure front access would be sufficient, pretty much like most tanks are situated. You would still have decent access to part of the back as well though, 58" out of 90" is basically two thirds so most of the tank can be access from behind as well.

Just a quick thought for the shower, if you extend the bathroom wall 6" down the page, and center a 36"x36" shower pan on the drain and put a 12"x36" bench on bottom of page side you'll gain a little more clearance (6") for the tank would negatively effecting anything else.
