I am in the midst of an owner-build that started last November. My pool is 65’ long, 10’ wide lap pool with a raised hot tub at the end.
After our waterline tile was installed we had a lot of rain that filled the pool with a few feet of water. I noticed that the waterline seemed a little higher at one end of the pool. This concerned me, so I checked the level of the waterline tile, first with a homemade water level and then ultimately with a laser level.
It appears that the waterline tile is not level. From one end of the pool to the other (65') the level appears to vary 5/8” to maybe 3/4”. This wouldn’t be so bad if I were using a 6x6 tile, but our tile is a pattern that is four tiles high, each tile being 1.5” tall. The variation from one end of the pool to the other is approximately half the height of one tile. I am concerned that this is going to drive me crazy once the pool is complete and filled with water.
I told my tile guy about my concerns and, of course, he says it is within industry standards. I told my plumber about this, and he says that it is not acceptable and the industry standard is more like 1/4”.
My dilemma is whether to fix this now or just finish the pool. If this is a problem, it will be much cheaper to fix it now than after the pool is plastered and filled. So basically I am looking for opinions and recommendations. How level should waterline tile be? Is this within industry standards or should I fix this before proceeding?
Thanks in advance!
