Wooden pools have grown increasingly popular in recent years — and it's easy to see why. Whether above-ground, semi-inground, or in-ground, they combine natural aesthetics, solid construction, and genuine backyard presence. Here's everything you need to know about building one.
Permits and Regulations for Wooden Pool Installation
For an above-ground wooden pool with a basin surface area over 215 sq ft (20 m²), the wall height must not exceed 3.1 inches (8 cm). If you want more depth, partial or full burial is required.
Above-ground models generally don't require administrative procedures, but always check whether your land is subject to a land use plan (POS) or local urban plan (PLU). In protected or classified areas, installation is possible provided the pool remains uncovered, is removable, has a surface area under 215 sq ft, is positioned at least 10 ft (3 m) from property lines, and has a wall height under 3.3 ft (1 m).
A building permit is required for pools over 1,076 sq ft (100 m²), or when installing a shelter taller than 5.9 ft (1.80 m). A work declaration is needed for in-ground or semi-inground pools between 108 and 1,076 sq ft (10–100 m²), and for above-ground pools over 108 sq ft (10 m²). No declaration is required for an above-ground wooden pool installed for no more than 3 months per year.
Kit vs. Custom-Made — Choosing Your Build Type
Wooden Pool Kit
Kit pools include all necessary components for installation. No excavation needed — just prepare a flat, level surface. Install geotextile protection (leveled gravel or sand bed) as a base. Depending on pool size and shape, a reinforced concrete slab or metal support shoes may be needed. The manufacturer's manual covers all specifics.
Custom-Made Wooden Pool
Custom models also arrive as kits, but offer greater flexibility in shape, dimensions, and finish. Assembly follows the same principle — place components per the manufacturer's instructions. Tutorials are a helpful complement to the included manual.
Step-by-Step Assembly Guide
Step 1 — Check and Store Delivered Materials
Upon delivery, verify all components are present and in good condition. Kit contents typically include structural elements, filtration accessories, and optional extras. Store components in order of assembly priority in dry, protected conditions.
Step 2 — Choose the Right Location
Select a flat, stable surface with no subsidence risk. Prioritize a sunny, wind-sheltered spot away from trees and overlooking neighbors. Ensure proximity to a water supply and electrical outlet for the filtration system.
Step 3 — Prepare the Ground
Mark out the location with an additional 20 inches (50 cm) margin. Remove all pebbles, roots, and other debris. Level the ground thoroughly. Lay geotextile protection or pour a concrete slab to prevent moisture and weed regrowth.
Step 4 — Assembly
Following the included assembly plans: erect the walls starting with the panel that will house the skimmer, taking wind direction into account. Install coping supports (triangular or angled wood pieces) with correct spacing — copings are fragile, handle carefully. Install liner rails and wall felt (leaving a 10-inch / 25 cm screw gap). Place the return jet and skimmer, then fix the uprights or leg supports. Lay the bottom and wall felt, trimming excess with a utility knife. Install the liner to ensure full watertightness. Finish by installing the coping so it overlaps approximately 0.8 inches (2 cm) inside the basin.
Step 5 — Fill and Finish
Fill the basin to just below the first sealing piece. Reinstall the return nozzle and skimmer. Install the ladder, connect the filtration system, fill to the correct level — and your wooden pool is ready to enjoy.
A wooden pool adds real value to your backyard — combining elegance, natural charm, and surprisingly fast installation. Follow the steps, respect the regulations, and you'll have a beautiful relaxation space for seasons to come.
FAQ: Building a Wooden Above-Ground Pool
What wood should I use to build an above-ground pool?
For a moisture-resistant wooden above-ground pool, use Class 4 treated timber (pressure-treated): treated Scots pine, black locust, or Accoya. These woods withstand permanent water contact. Avoid untreated wood which rots within 1–2 seasons. Some above-ground pools use larch, which is naturally durable (Class 3 without treatment).
How much does it cost to build a wooden above-ground pool?
A DIY wooden above-ground pool costs €500–3,000 in materials depending on size and wood quality. Ready-to-assemble wooden pool kits (Ubbink or BWT-type) cost €800–5,000. Add the cost of the liner (€100–400), the pump (€50–200), and other accessories.
Does a wooden above-ground pool need a liner?
Yes, a liner is essential to make a wooden above-ground pool watertight. PVC liner (0.5–0.75 mm) is the most common. Special liners for wooden pools with reinforced support edges are available. The liner is cut to the exact dimensions of the basin. Its lifespan is 10 to 15 years. A torn or punctured liner can be repaired or replaced.
Does a wooden above-ground pool require planning permission?
Yes, if the volume exceeds 10 m³ or if the pool is intended to remain for more than 3 months (any pool with a permanent liner falls into this category). A prior work declaration is required between 10 and 100 m². Check with your local council before starting work to verify local planning regulations.
How long does it take to build a wooden above-ground pool?
Building a wooden above-ground pool from a kit takes 1 to 3 days for two experienced people. Without a kit, allow 3 to 5 days for a confident DIYer. The main steps are: ground preparation (half a day), frame assembly (1 day), liner installation (2–4 hours), and hydraulic equipment setup (2–4 hours).
