Replacing kitchen countertops sounds straightforward until you get into the details: sink cutouts, seam placement, appliance clearances, backsplash height, and the reality that older homes in San Antonio rarely have perfectly square walls. In 2026, homeowners are still remodeling at a strong pace, and industry forecasts expect U.S. homeowner remodeling spending to reach record levels in early 2026. (Harvard Joint Center for Housing Studies) That demand can tighten schedules, which makes planning even more important.
If you want to avoid the mistakes that lead to rework, delays, and change orders, treat your countertop project like a small construction job, not a décor update. Bellezza Surfaces builds its process around design, fabrication, and installation, which is where most “surprise costs” can be prevented.
Mistake 1: Choosing Stone Before You Lock the Layout and Use Zones
The most common misstep is picking a slab based on a photo, then trying to force it into a layout that was not planned for how you cook and move. In many San Antonio kitchens, the island becomes the hub for prep, homework, and entertaining, and that changes what you need from the surface.
Pro tips that prevent regrets:
- Walk your current kitchen and note the pinch points: trash pull-out, fridge swing, dishwasher open space, and where you land groceries.
- If you are changing the sink size or moving plumbing, make those decisions before templating.
- Think about edge profile and thickness as part of the design, not as a last-minute add-on.

Mistake 2: Underestimating Seam Placement and Visible Transitions
Seams are normal, especially in larger kitchens, but poor seam planning is one of the fastest ways to make a new countertop look “patched together.” This matters in open-plan San Antonio homes where the kitchen is visible from the living area.
Where seams go wrong:
- They land at the center of the main sightline (front door view, living room view, or island seating view).
- They cut through bold movement in the stone.
- They end up too close to sink cutouts or cooktop cutouts, which can create weak points.
Pro tips for better seam outcomes:
- Ask your fabricator to show seam locations on the template plan before the slab is cut.
- If you are choosing a material with strong veining, request that the seam location supports the pattern flow, especially on islands.

Mistake 3: Treating the Sink and Faucet as “Later Decisions”
In countertop work, “later” often means expensive. Undermount sinks, farmhouse sinks, workstation sinks, and specialty faucet hole layouts all change the cutout plan. If you are a new homeowner or a builder trying to keep a schedule moving, this one detail can create avoidable delays.
Pro tips for sink success:
- Purchase the sink and faucet early enough for the fabricator to confirm specs.
- Confirm if you want a single hole, widespread, or filtered water tap setup before drilling happens.
- Think about daily cleaning. Some sink reveal styles make wiping crumbs into the sink easier than others.

Mistake 4: Skipping Prep Work That Protects Cabinets and Prevents Install-Day Problems
Countertops rely on what is underneath them. If cabinets are not level or adequately supported, you can end up with fit issues, visible gaps, or stress points that show up later. This is especially relevant in older San Antonio homes where floors may have settled over time.
Pro tips before templating day:
- Make sure all base cabinets are installed, secured, and level.
- Confirm your appliance models and final locations (range, cooktop, hood, and fridge).
- Decide backsplash plans: full-height stone, tile, or a short splash, since that affects how the countertop meets the wall.
Planning matters because homeowners are putting real time into kitchen projects. Houzz research has noted that kitchen renovations often involve long planning timelines relative to the actual construction work. (Real Simple)
