How much will it cost to replace a pool lining in 2026?
If your pool is leaking, the tiles are coming loose, or the pool surface has stains that won’t come out no matter what treatment you use, it’s time to replace the pool lining. This is the most common renovation we perform—and also the one that raises the most questions about cost. Here are the actual figures for 2026, broken down by material.
Estimated prices for an 8x4-meter pool
For a standard 8x4-meter pool (about 68 m² of interior surface area, including the bottom and walls), these are the price ranges we’re seeing in Spain in 2026:
• Pool paint: between €1,500 and €3,000, including labor. This is the most economical option, but also the least durable: it needs to be redone every 2–4 years.
• Liner: between €3,000 and €4,500. Factory-welded 0.75 mm PVC liner. Suitable for tight budgets, with a lifespan of 8–12 years.
• Reinforced liner: between €4,000 and €6,500 installed. 1.5 mm reinforced PVC with polyester mesh, welded on-site and adapted to any pool shape. It guarantees complete watertightness: this is the solution we recommend when there are leaks, and it lasts 15–20 years or more.
• Mosaic tiles: between €5,500 and €9,000. The timeless classic. Aesthetically flawless, but it requires the substrate to be in very good condition, and its future repair costs are the highest.
Price per square meter (2026)
If your pool isn’t an 8x4, you can estimate the cost using these ranges per square meter installed: paint €12–18/m², liner €35–50/m², reinforced membrane €50–70/m², and mosaic tile €70–100/m². Added to this are fixed costs such as draining the pool, preparing the substrate, and installing the mounting profiles—which is why the approximate totals above are higher than a simple multiplication by m².
What the quote includes (or should include)
A professional pool resurfacing project includes: draining and cleaning the pool, repairing and preparing the substrate (cracks, holes, loose areas), installation of perimeter profiles, installation of the new tiling, sealing of special components (skimmers, spotlights, nozzles, drain), and filling and commissioning. Be wary of estimates that do not detail these items: that’s where cost overruns tend to occur.
Which lasts longer?
Paint is the cheapest option today but the most expensive over a 10-year period, because it needs to be repainted every few seasons. A liner offers a reasonable balance. Well-maintained mosaic tiles can last over 20 years, although spot repairs are expensive and frequent in pools with high usage. Reinforced membrane is the only system that combines a long service life (15–20 years or more), guaranteed watertightness even in pools with microcracks, and virtually no maintenance. That’s why it’s the lining we install most often, both in older pools undergoing renovation and in new construction.
Signs That Simply Painting Isn’t Enough
If the water level drops more than 3–5 mm per day for no apparent reason, if moisture appears around the pool, or if the tiles sound hollow when tapped, the problem lies beneath the lining. In these cases, simply painting over the surface is a waste of money: reinforced membrane solves the watertightness issue at its root without the need for major construction work. We explain the differences in detail in our comparison of reinforced membrane vs. liner and in our guide on how much it costs to renovate a pool.

Frequently Asked Questions
How much does it cost to replace a pool’s lining?
For an 8x4-type pool, between €1,500 and €3,000 with paint, €3,000 to €4,500 with a liner, €4,000 to €6,500 with reinforced membrane, and €5,500 to €9,000 with mosaic tiles (estimated prices for 2026, including labor).
Which pool lining lasts the longest?
Reinforced liner and mosaic tile are the most durable (15–20 years or more). The difference: reinforced liner also ensures the pool is watertight and requires almost no maintenance; mosaic tile requires a substrate in good condition and periodic repairs.
When is simply painting the pool not enough?
If the pool is leaking water (more than 3–5 mm per day), there’s moisture around it, or the tiles sound hollow, the problem lies beneath the lining: painting over it won’t fix it. In those cases, reinforced liner is the definitive solution.
