What is the cost to paint a pool house or cabana exterior and interior in Ottawa?

Painting a pool house or cabana in Ottawa typically runs $1,500 to $5,500 for a combined interior and exterior project, though the range is wide because pool houses vary enormously in size, construction material, and the moisture conditions they're exposed to. A compact 10x12 cedar cabana with a simple interior is at the lower end; a fully finished 400-square-foot pool house with change rooms, a bathroom, and a bar area will push toward the top of that range or beyond.

The exterior cost is where Ottawa's climate and the pool environment create some real complexity. Pool houses face a brutal double threat: Ottawa's freeze-thaw cycles attacking the paint film from one direction, and pool water — chlorine vapour, splash, and high ambient humidity — attacking it from the other. Standard exterior acrylic latex, even premium lines like Benjamin Moore Regal Select or Sherwin-Williams Duration, will underperform on a pool house if applied without the right prep and primer strategy. For wood-sided pool houses, a high-quality bonding primer followed by a moisture-resistant exterior acrylic is the minimum. For stucco or concrete block construction, an elastomeric coating ($80 to $120 per gallon) is often the smarter choice — it flexes with freeze-thaw movement and creates a more water-resistant film that stands up to the pool environment far better than conventional paint.

Exterior painting on a typical pool house structure runs roughly $800 to $2,500, depending on size, surface condition, and material. If there's significant wood rot, peeling from past moisture infiltration, or failing caulking around windows and doors, budget another $300 to $800 for proper prep and repairs — skipping that work means the new paint fails within a season or two.

Interior painting is where the pool house diverges sharply from a typical room. Change rooms, shower areas, and any space near the pool itself need mould-resistant primers and paints as a baseline, not an upgrade. Humidity levels in these spaces can be extreme during Ottawa summers, and standard interior latex will blister and peel within a year if the surface prep and product selection aren't right. A bathroom-grade or kitchen-grade sheen (satin or semi-gloss) with a mould-inhibiting additive or a purpose-built product like Benjamin Moore Aura Bath and Spa is the right call. Interior costs for a pool house typically run $700 to $3,000 depending on square footage, ceiling height, and how many distinct areas (open lounge space versus tiled change room versus bathroom) need different treatment.

One thing Ottawa homeowners sometimes overlook: if the pool house was built before 1978, test for lead paint before any sanding or scraping — this is non-negotiable under Ontario Regulation 278/05, and the testing cost ($200 to $400 for a professional assessment) is money well spent. Also confirm whether your property falls within one of Ottawa's heritage conservation districts, though pool houses are less commonly subject to heritage restrictions than primary residences.

For a project with this many moisture and durability considerations, getting quotes from painters who have specific experience with pool structures is worth the effort. You can browse painting contractors through the Ottawa Construction Network directory at justynrookcontracting.com/directory — when reaching out, mention the pool house context specifically so you can gauge whether a contractor has dealt with similar conditions before.
