Hot Tub Installation in Hamilton, Burlington & Oakville
Antoine installs hot tubs: the pad, the placement and the landscape around them, planned with your electrician.
Quick answer
A 3–7 seat tub sits on a 4 in concrete slab with wire mesh; larger tubs and swim spas on 5–6 in with #4 rebar (Sundance Spas Canada). Filled tubs weigh about 3,000–6,000 lb, so a standard deck rated 40–60 lb/sq ft needs engineering. The electrician comes before the pad because the 2024 OESC requires a copper bonding ring set in the pad. A locked cover rated about 90 kg replaces a fence in Hamilton and Oakville (Burlington issues an $87 hot tub permit).

What goes under a hot tub
How to read this: A side view of a hot tub sitting on its base. Pick a base type to see what goes underneath.
- 4 in concrete slab, wire mesh
- Compacted base
- Copper bonding ring, 450–600 mm out from the tub
Concrete slab, 3–7 seats: A 4 in concrete slab with wire mesh (Sundance Spas Canada). The electrician is engaged before the pad is poured, because a permanently installed tub needs a copper bonding ring set 450–600 mm out from the unit (ESA Bulletin 68-8-4, May 2026).
- Concrete slab, 3–7 seats: A 4 in concrete slab with wire mesh (Sundance Spas Canada).
- Concrete slab, 8+ seats or swim spa: A 5–6 in slab with ½ in (#4) rebar for 8+ seat tubs and swim spas (Sundance Spas Canada).
- Paver pad: Heavy-load pavers on 1 in of sand over a 4–6 in compacted base (Sundance Spas Canada).
- Framed gravel pad: A framed crushed-stone base compacted in 2 in layers (Sundance Spas Canada).
Load check
Will my deck hold a hot tub?
How to read this: Enter your hot tub's details. The tool adds up the tub, water and people, then divides by the footprint to show the load per square foot.
5,186 lb filled load · 105.8 lb/sq ft
Water 3,336 lb + people 1,050 lb + tub 800 lb, over 49 sq ft.
Above the 40–60 lb/sq ft a typical residential deck is rated for: this needs engineering.
Formula: water weight = US gallons × 8.34 lb (or litres × 1 kg ≈ 2.2 lb); total ÷ footprint = load per sq ft. Typical residential deck rating 40–60 lb/sq ft; Sundance Spas Canada says a deck must handle 100–125 lb/sq ft. Illustrative estimate, not engineering.
Worked example: a tub weighing 800 lb dry, holding 400 US gallons (3,336 lb of water), with 6 people at 175 lb (1,050 lb), weighs about 5,186 lb filled. On a 7 × 7 ft footprint that is about 105.8 lb/sq ft, above the 40–60 lb/sq ft a typical deck is rated for. Example inputs are illustrative, not a specific model.
Before delivery
Placement checklist
- Pad extends 6–12 in past the tub (Sundance Spas Canada).
- 18–24 in of service access around the cabinet.
- Delivery path: measure gates and side yards.
- Hard-wired 240 V recommended for Canadian winters, because 120 V plug-and-play units can't heat and run jets at once (Hydropool).
- ESA notification by a Licensed Electrical Contractor.
- Copper bonding ring set before the pour.
- Drainage graded away from the pad.

Hot tub installation FAQ
What base does a hot tub need?
Sundance Spas Canada specifies a 4 in concrete slab with wire mesh for 3–7 seat tubs, and a 5–6 in slab with #4 rebar for 8+ seat tubs and swim spas. A paver pad uses heavy-load pavers on 1 in of sand over a 4–6 in compacted base. The pad should extend 6–12 in past the tub on every side.
Can I put a hot tub on my deck?
Often not without engineering. Filled tubs weigh about 3,000–6,000 lb, and large models and swim spas can exceed 10,000 lb. A standard residential deck rated 40–60 lb per sq ft needs engineering to carry one, and Sundance says a deck must handle 100–125 lb per sq ft. Our load check gives an illustrative estimate, not engineering.
Why does the electrician come before the pad?
Under the 2024 Ontario Electrical Safety Code, a permanently installed hot tub needs a copper bonding ring set in the pad, 450–600 mm out from the unit (ESA Bulletin 68-8-4, May 2026). The ring has to be placed before concrete is poured, and the work needs an ESA notification by a Licensed Electrical Contractor, so the electrician is engaged first.
Should my hot tub be 120 V or 240 V?
Hydropool, an Ontario manufacturer, recommends hard-wired 240 V tubs for Canadian winters, because 120 V plug-and-play units can't heat and run the jets at the same time. A hard-wired tub needs electrical work by a Licensed Electrical Contractor with an ESA notification filed before work starts, so plan the circuit together with the pad.
Do I need a fence or permit for a hot tub?
In Hamilton the pool by-law counts hot tubs, but a locked rigid cover rated 90 kg replaces the fence. Oakville needs no permit or fence with a locked cover rated 90.72 kg. Burlington issues an $87 hot tub permit for tubs under 8 m², with a lockable lid. Confirm current rules with your municipality before building.
How much does a hot tub installation cost?
Hydropool, an Ontario manufacturer, puts a typical all-in project at about CA$18,000–$20,000: around $14,000 for the tub (range $6,500 to $25,000+), about $2,000 for the pad, about $2,000 for electrical and under $500 for delivery (Nov 2024 article, 2026 pricing). These are manufacturer figures; your exact price comes from an on-site quote.
How much space does a hot tub need around it?
Leave 18–24 in of service access around the cabinet, and build the pad 6–12 in larger than the tub on every side (Sundance Spas Canada). Measure gates and side yards before delivery so the tub can reach the pad, and grade the area so water drains away from the pad rather than toward it or the house.
Is a hot tub near the Niagara Escarpment treated differently?
Parts of Ancaster, Dundas, Flamborough and rural Burlington sit in the Niagara Escarpment Development Control Area. A spa there needs an NEC permit unless it meets every exemption test, including a water area of 13 m² or less. The NEC page is being updated under the new O. Reg. 225/26, so verify the current rules before building.
