Why Most Spa Additions Fail
Adding a spa to an existing pool sounds simple. It’s not. Poor planning leads to mismatched styles, awkward placement, plumbing nightmares, and spas that look like afterthoughts instead of intentional design. Many contractors treat spa additions like separate projects, ignoring how they flow with your pool and yard.
Four Mistakes That Ruin Spa Additions
- Poor Integration
The spa looks tacked on instead of purposefully designed. Mismatched finishes, awkward transitions, and clashing styles that make your backyard look disjointed. - Wrong Placement
Spas stuck in corners where nobody uses them, blocking views, or taking up space that could’ve been better utilized. Location matters more than most people realize. - Inadequate Systems
Undersized heaters that take forever to warm up, weak jets that don’t provide real therapy, and pumps that can’t handle the load. Cheap components mean constant frustration. - Hidden Costs
Contractors lowball estimates, then hit you with surprise charges for plumbing, electrical, permits, and structural work. What started as affordable becomes a budget disaster.
The result? A spa you rarely use, a yard that looks worse, and thousands spent on something that didn’t deliver what you wanted.
At Landmark Custom Pools, we design spa additions that look intentional, function perfectly, and integrate seamlessly. We’ll assess your space, understand your vision, and create a spa that feels like it was always part of your pool. Your backyard can be everything you want it to be.

Don’t Take Our Word for It
When homeowners want spa additions done right, they choose Landmark Custom Pools. Here’s what they have to say:
“All we can say is wow! From the beginning, Mark helped us design the pool of our dreams. Even redoing it because my wife changed her mind about the form we wanted. He made sure that we were fully happy with what we chose. When it came to picking our materials, he walked us through what would look good based off our choices. Once that process was done, we met with Raul. He’s a pool magician! His team was quick and efficient, aside from rainy days they were out there getting work done. Raul was always quick to respond, if you called and he was unavailable he would let you know and then follow up as soon as he was free. He was always responding to texts and all the questions we had. Mark and Raul are a power duo! They know their pools and make sure you are getting what you want and that you are completely happy. They both truly have a passion for their craft, and make sure to touch base with you constantly so that you have a great experience. 100/10 would recommend. If we ever needed another pool, wouldn’t go with anyone but them. You will not be disappointed.”
-Ramsey, T. ⭐⭐⭐⭐⭐
“I recently had a pool built by Landmark Custom Pools and am extremely happy with the results. Raul, in particular, was fantastic—very responsive, helpful, and professional throughout the entire process. The team communicated well, kept me updated on progress, and delivered a beautifully crafted pool. Despite a few weather delays, everything went smoothly. They also provided helpful maintenance advice after completion. I highly recommend Landmark Custom Pools, especially Raul, for anyone looking to build a custom pool in Houston.”
-Ermecheo, J.A. ⭐⭐⭐⭐⭐
“Mark is an incredible business owner and Landmark is nothing but top notch! As a real estate broker who represents builders, I often need Mark’s expertise for pool projects. He always makes himself available in a timely manner, provides efficient quotes and builds and designs timeless, quality pools. I recommend him to anyone who tells me they want to build a pool. He’s the only one I trust to go to!”
-McCauley, A. ⭐⭐⭐⭐⭐
“I cannot say enough good things about Landmark Custom Pools! From start to finish, the team exceeded our expectations in every way. Their professionalism, attention to detail, and commitment to quality truly set them apart. From the initial consultation, they took the time to understand our vision and provided creative suggestions to make it even better. The design process was seamless, and the final product was stunning—our backyard has truly been transformed into an oasis.”
-Della Porta, M.F. ⭐⭐⭐⭐⭐
“Loved working with Mark and Raul. They made the entire process seamless and easy. Our pool is absolutely gorgeous and we have to thank Landmark for making this happen.”
-Morton, A.J. ⭐⭐⭐⭐⭐
“Landmark Custom Pools did an amazing job! Mark’s design was stunning and completely transformed our backyard. He really listened to what we wanted and delivered beyond our expectations. The quality and attention to detail were top-notch. Highly recommend if you want a beautiful, custom pool!”
-Sam, P. ⭐⭐⭐⭐⭐
“Landmark Pool did a great job building our backyard pool. The design process was straightforward, and they listened to our ideas, incorporating most of what we wanted into the final layout. They were straightforward with the timeline expectations and didn’t commit to anything unless they were confident that they could come through with it.
There were a few hiccups along the way—the permit process took a lot longer than expected in The Woodlands, and there were some delays with laying down the turf due to weather; however, neither of these could be controlled by Landmark Pool.
We’re happy with the pool and our kids love using it. The pool itself is beautiful yet functional, and it blends well with our backyard space. Mark and Raul are honest guys who delivered a quality product!”
-Jung, K. ⭐⭐⭐⭐⭐
