This is a nice project you have going. Very intricate with the in-pool patio.
Dont feel bad about how its taking, or some of the issues that pop up. It's pretty much normal pool building stuff.
It is very rare, that the build goes 'as planned'. It always seems to be something that causes a problem.
That pool is almost exact except the 3 pads you got.
The groute uses on the pool tiles is by Laticrete Permacolor Groute in shade Midnight Blue.
