No place to do that where this is located unfortunately or I would've... but that also doesn't help answer my question lol 

@Carl C. Essentially what I am asking is, as soon as I turn the Hot and Cold water back on in that bathroom(where I converted from C to Pex), I need to finish putting cement board on the wall, etc. which will then make it so I don't have access to those shut offs anymore. Once the water is on it mixes hot and cold with just the rough in valve installed. Just didn't know if it was OK to install the cartridge sooner (before tilework was done) to avoid having the water mixing. Every video I watch they seem to all install the cartridge / fixtures as a last step.

I am renovating my small full bathroom (shower is only 3' x 3'), bathroom is like 5' x 5'.

I have it fully gutted and replaced subfloor where necessary. I have switched the plumbing from copper to pex and have the new rough in valve installed. When I turned the water back on the rough in valve I am assuming is mixing the hot and cold water so we dont have hot water anywhere. Is it OK to install the cartridge now before the tile is installed or how does one avoid this issue while doing the work DIY and not able to work on it 10 hours a day where its ok to not have hot water for 1/2 days.

I have shutoff valves where I made the copper to pex conversion but I need to turn the water back on... seal the wall up with cement board so I can continue and waterproof it, tile it, etc. Just not sure how fast I can get it done and dont want to not have hot water for weeks lol.

Probably an easy question but I cant really find any info about what people do to avoid this. The Rough in valve does NOT have shut off valves integrated on it.

Thanks for any input!
