Replacing Waterline Pool Tiles: Choosing a New Border for an Existing Pool

A pool tile replacement project starts with two decisions: what needs repair, and what you want the finished border to look like. A new waterline can change the pool’s appearance, but choosing the tile is only one part of the work. Have a pool professional assess the existing edge before ordering materials or scheduling removal.

This guide focuses on choosing and ordering replacement tiles. The contractor should determine the preparation, repairs and installation system required for your particular pool.

Decide Between a Small Repair and a New Border

If only a few tiles need attention, identify the original design, dimensions, thickness and finish first. Compare an intact tile with the proposed replacement. A similar photograph or a matching nominal size does not guarantee that the new tile will fit the same space or match an aged glaze.

If an exact match is unavailable, discuss a deliberate design change with the contractor: replacing a complete run, creating a defined accent section or renewing the whole waterline. Choose the approach after the condition of the surrounding tile and substrate has been assessed.

Record the Existing Layout

Take an overall pool photograph and close views of the coping, tile rows, inside and outside corners, curves, skimmers and spa connections. Note which surfaces will remain. Those fixed finishes become the reference for choosing the new border.

• Measure the perimeter of every area receiving tile.
• Record the height of the existing tiled band.
• Identify separate spa walls or raised sections.
• Measure an intact tile and the current joint spacing.
• Ask the installer about tile thickness and transitions to retained finishes.

Check Actual Dimensions Before Choosing a 6×6 Replacement

The term 6×6 pool tile describes a common nominal format. Designs in Balian’s collection are also listed as 15 × 15 cm, approximately 5.91 inches. Confirm the actual dimensions of the chosen tile and the proposed joint width rather than assuming it matches your old six-inch layout.

For a preliminary one-row estimate, a nominal six-inch module uses about two tiles per linear foot. The final count must account for the actual layout, cuts, pattern repeat and spares. Our 6×6 porcelain pool tile page explains the starting calculation.

Choose a Border That Works with the Finishes You Keep

A renovation often keeps the coping and paving in place. Compare tile samples with those materials first. Dark blue can create a strong outline beneath pale coping; a light background can give painted detail more separation. Green or turquoise accents can connect the waterline with planting, while a monochrome pattern gives a different rhythm.

Explore blue pool tiles, green pool tile designs and black and white borders. Our guide to matching pool tile and coping helps you compare the complete palette.

Review the Complete Pattern Repeat

Ask to see neighboring tiles or a layout image. A continuous vine, wave or geometric border may need a specific orientation. Discuss how the repeat will turn corners, meet skimmers and finish at a spa. This review is especially useful when a replacement border must fit between surfaces that will remain.

Use our sample comparison checklist to review color in your own light. Confirm the exact design name and colorway when you approve the order.

Separate the Tile Quote from the Installation Quote

A tile supply quote should identify the design, quantity, unit price and delivery details. The contractor’s quote should explain the removal, disposal, substrate repair, setting materials, grout, movement joints and any work to adjacent finishes included in the project.

Ask what happens if removal reveals additional repairs and how those would be priced. Confirm the tile and installation system are suitable for the pool construction and exposure conditions. Coordinate delivery and the contractor’s schedule before setting a start date.

Order Spares with the Main Batch

Ask your installer to calculate a project-specific allowance for cuts and future repairs. Keep spare tiles labeled with the design and order details. Retaining the same batch can be useful if a tile needs replacement later, especially for a decorated border.

Browse Balian’s hand-decorated porcelain waterline tiles, then contact us about your replacement border. Send photographs of the existing edge, your preferred designs, perimeter, number of rows, contractor-confirmed dimensions and delivery ZIP code. For a small matching repair, include clear photographs and measurements of an intact tile so we can discuss whether a suitable option is available.
