New Cage Location

Hi everybody! My guinea pigs, Jupi & Boo Boo have been living in a pet store cage in a bathtub in a bathroom we do not use anymore for the past two months, and I feel they deserve a C&C cage. My bunnies have a huge 4 h x 3 w x 4 l C&C condo I built in our living room, so the guinea pig's options are limited. I have the option of my room and the bathroom. My room would be hard to persuade, and would be right by a window and I would be sleeping nearby to the cage which may disturb my sleep.

The other option is the bathroom. It is a guest bathroom we rarely -ever- use, usually just to wash our hands in the tap now and then. The guinea pigs have had their cage in the bathtub there since we had them, and now that I have some free time, I'd like to upgrade them. We recently went out and bought a wooded board to cover he expanse of the bathtub and use the tub area as storage underneath the cage. The cage is currently sitting on the board and is about equivalent to a 1 x 3, but the board can fit as measured a 2 x 4 c&c cage. There is a window higher up on another wall, so there is enough light and ventilation, and it in located in a moderate activity area. The location is very suitable for me, as the tiling is much easier to clean than my own carpet and no stress about spills or accidents.

So the question is: Do you think the cage being elevated on a board in the unused bathroom would make for a suitable living place? They would have a 2 x 4. No humidity or drastic temperature changes, I think it would be okay. Just wanted to get your opinions here before I went out and bought anything. Thank you all in advance, have a good night. I have included recent pictures of their general setup.
