HDB vs condo vs landed
HDB
Usually at the lower end when replacing an existing instant heater, since the power point and water connection are already there.
Condo
Similar to HDB for a swap. If the unit was built with a storage heater only, switching to instant may need a new point at the shower, which adds LEW work.
Landed
Priced per bathroom. Upper-floor bathrooms with weak pressure often need a pump model, which costs more to buy.

Water heaters buying guideInstant water heater installation price: common questions
Why do retailers quote less for installation than plumbers?
Some retailers offer a basic installation when you buy the unit from them, often limited to a straight swap at an existing point. A plumber's quote may also cover removing the old unit, a new bracket position or a new hose and rail. Compare what each includes.
How much more does a pump or rain-shower model cost?
Labour is similar, but the unit costs more. Basic instant heaters start around $110, while pump and rain-shower models sit at the top of the $110–380 range or above it.
