Powder room refresh ($4,500-$8,500): 90-110% ROI. High visibility, low cost, broad appeal. Main bathroom mid-range ($18,000-$32,000): 70-90% ROI in most Ottawa neighbourhoods. Premium primary ensuite ($40,000-$60,000): 50-75% ROI — diminishing returns past mid-range for resale-driven projects. Adding a new bathroom to a home with only 1-1.5 bathrooms: 100-150% ROI because Ottawa buyers heavily penalize sub-2-bath homes. Adding a 4th or 5th bathroom: minimal ROI past 3 bathrooms.
Pricing by type: powder room refresh $4,500-$8,500, full powder room $8,500-$18,000, main 3-piece bathroom $10,000-$28,000, main 4-piece $22,000-$60,000, primary spa ensuite $32,000-$90,000, basement bathroom $9,500-$28,000. Median main bathroom remodel: $24,000-$32,000.
Powder room: 1-2 weeks. Main bathroom gut renovation: 3-5 weeks. Primary spa ensuite: 5-8 weeks. Add 1-2 weeks for delayed material delivery, custom glass enclosure measurement, or hidden-condition discovery in older Ottawa homes.
Adding a powder room to a home with 1-1.5 baths returns 100-150% in Ottawa. Powder room refresh returns 90-110%. Main bathroom mid-range renovation returns 70-90%.

Yes for any work that adds plumbing fixtures or moves drain locations. Like-for-like fixture replacement (toilet for toilet in same location, vanity for vanity) usually doesn't require a permit. Adding a new bathroom always requires a building permit, plumbing permit, and electrical permit via ESA.
Plumbing and electrical work require licensed trades in Ontario. Tile work is DIY-feasible for skilled homeowners but waterproofing is the single most failed DIY element. Mixed projects (DIY demolition, painting, accessory install + professional trades for plumbing/electrical/tile) can save 15-25% of total cost.
