Is building an access panel in an adjacent to the bathroom closet allowed by the code?

I have an alcove shower that has the shower column on a wall that is adjacent to a closet for another room -see the picture I could simply run the supply lines for the shower column that sits on that wall without shutoff valves but I am thinking that since this will involve little effort and I would be using Sharkbite fittings to transition from copper to pex in that wall I could use shutoff valves and build an access panel in the closet in the adjacent room. I am in Ontario. Is this against the code ?
here is the view from the alcove

I see nothing wrong with adding an access panel. I wish more people would have them installed

Check with your local building official.

I think In Ontario you must have plumbing access panels( at least that is what i was told ) to allow for maintenance, inspection, and repair of concealed components like valves, clean-outs, and unions without cutting or damaging surrounding wall/ceiling materials. But i could be wrong.

A lot of times, when looking for a leak in a wall, we remove the medicine cabinet in the bathroom and look up and down and side to side to help locate a leak, rather than breaking lots of walls .

In Manhattan, the college of music had cleanouts buried in concrete columns and under the cement slabs.

When we located them, we installed deck plates and access doors for the ones in the wall

I’d do the access panel. I don’t see the downside, especially if you’re putting shutoffs or transition fittings in that wall.

Code or not, future-you will be very happy you didn’t have to perform drywall surgery just to reach a valve.

Just make sure the panel is actually accessible and not buried behind shelves full of mystery closet stuff.
