Request for advice on spa niche issue during pool build
I'm looking for advice on an issue with our spa jet niches during pool building. Our spa jets niches are currently set between 1" and 1 3/4" out from the shotcrete spa wall. Some of these are just at or below the waterline tile so there's not much room to fill in with plaster. The pool builder is discussing the options and is working with us to get the issue resolved.
I'm looking for advice on the best way to resolve this.
The current proposed solution is...
For the lower jets: add extra plaster as needed around the lower jet niches so that they are flush with the plaster
For the upper jets that are close to the waterline tile: chisel out a bit of the wall so they can get the current niches out and then cut the back piping of the jet niches a little as needed to get the jets recessed properly.
We have one jet that is high enough that the plastic housing of the wall fitting will overlap the waterline tile once it is set in the niche. Can that one sit on the waterline tile or does that need a more major fix?
Most of this issue happened because the spa was accidentally shot with a thicker wall (13-14") when it was supposed to be 11-12" thick to accommodate the 12" travertine coping. They shot the spa wall with the plaster niches in place. They then cut away at the spa interior wall to get the wall thickness to the right dimensions but then the jet niches are left sticking out too far.
Questions I have:
1. Would it really be a problem (comfort and performance) for the spa jets niches to stick out a bit from the spa wall (might be as much as an inch)?
2. What would be the best way to fix this issue?
3. What are alternate reasonable solutions for this issue?
