Pool and Spa Combination Layout Guide
A spa attached to a pool isn't just a smaller, hotter section of the same water, it's a separate plumbing and heating zone layered into one design. The Woodlands Township Covenants require Design Review Committee approval for pool and backyard construction in nearly every village, and that review covers fencing, setbacks, and drainage as well as the pool itself.
Raised Spillover vs. In-Line
A raised spillover spa sits above the pool deck level with water spilling over its wall into the pool, giving a visual and sound feature in addition to a separate soaking space. An in-line spa sits at pool level, separated by a low wall or nothing at all, simpler and less expensive to build but without the spillover visual.
Separate Heating, Shared Pump (Usually)
A spa needs to heat and circulate independently from the main pool (so it can run hot without heating the whole pool), which usually means a separate heater zone and valve-controlled plumbing even when both share the same pump, a detail that gets engineered during design, not improvised later.
