Bathroom Vanity & Cabinet Installation — Toronto GTA

Expanded description (rendered as hero body + intro section)

A bathroom vanity is one of two things: a piece of furniture you keep for 25 years that turns the room into the showpiece of your home, or a stock-cabinet box you'll replace in 7 years when the painted MDF doors swell from steam exposure. The cabinet you choose dictates that future.

This page covers the premium custom-millwork side of bathroom cabinetry — full-bespoke vanities, custom medicine cabinets, integrated linen towers, and built-in storage solutions designed for Toronto and GTA premium-tier renovations ($8,000–$25,000+). For drop-in stock vanities from IKEA, Home Depot, Wayfair, or Lowes — fast 1-day installs in the $800–$3,500 range — see our dedicated [Vanity Installation](/services/kitchen-bath/vanity-installation) page.

RenoHouse partners with established Toronto-area custom millwork shops (Aya Kitchens, Florentine, Ariel Builders, Tailored Living) and our own in-house finish carpentry crew to deliver semi-custom and fully-custom vanity packages. The deliverables you'd expect at this tier: precise-fit to non-standard openings (older Toronto homes have anything-but-standard wall lengths), premium hardwood plywood box construction (not particleboard, not MDF), solid-wood or veneered solid-wood door fronts, Blum or Salice soft-close concealed hinges, full-extension soft-close drawers on undermount slides, dovetail drawer construction, premium hardware (Top Knobs, Restoration Hardware, Emtek), integrated lighting in toe-kicks or under upper shelves, integrated outlets and USB-C ports in drawer interiors, and finishes hand-applied with conversion-varnish or 2K polyurethane (not the spray laminate that fails in a steamy ensuite).

Pairing options include engineered quartz or natural stone vanity tops (Caesarstone Statuario Maximus, Cambria Brittanicca, Silestone Calacatta Gold, honed marble for those who accept etching), undermount or vessel sinks (Kohler, Toto, Lacava, Native Trails copper), and matching framed or LED-integrated medicine cabinets (Robern, Kohler Verdera, custom-fab to match vanity finish).

Serving Toronto, Mississauga, Brampton, Vaughan, Markham, Richmond Hill, Oakville, Burlington, Etobicoke, Scarborough, North York, and the surrounding GTA.

Custom vs Stock — Which Side Are You On?

If 4+ rows on the left are "yes" for you, you're a custom-millwork client and this page is yours. If 4+ rows on the right are "yes," see our [Vanity Installation](/services/kitchen-bath/vanity-installation) page for the faster, lower-cost route.

Material & Construction Spec

Box construction:

• Hardwood plywood (Baltic birch, maple, or cherry ply 3/4" or 5/8") — premium standard. Will not delaminate from bathroom humidity for 30+ years.
• Avoid: Particleboard or MDF box construction in any bathroom. MDF swells when exposed to repeated humidity cycles and screws strip. Stock IKEA/Home Depot vanities use particleboard with melamine wrap — fine for 7–10 years, then visible failure at the bottom corners.

Door front options:

• Solid wood (maple, oak, walnut, cherry) — premium grain, can be re-finished decades later.
• Hardwood plywood with solid-wood frame (Shaker style) — most stable in humidity, classic look.
• MDF painted (conversion varnish or 2K poly finish) — acceptable IF the finish is sprayed in-shop with proper sealing of all 6 sides. Cheap painted-on-site MDF fails fast.
• Veneered wood (rift-cut white oak, walnut, exotic species) — premium contemporary look. Veneer must be wrapped on all sides including back.

Drawer construction:

• Dovetailed solid-wood drawer boxes with Blum Movento or Salice Futura undermount soft-close slides — premium standard. 75–100 lb load rating.
• Avoid: Side-mount slides, particleboard drawer bottoms, stapled construction.

Hardware:

• Hinges: Blum Clip-Top or Salice 110° concealed soft-close. Adjustable in 3 dimensions. Lifetime warranty.
• Pulls/Knobs: Top Knobs, Restoration Hardware, Emtek, Atlas Homewares. Solid brass or stainless. PVD or living finishes (brushed brass, oil-rubbed bronze, polished nickel).
• Soft-close mechanisms on every door and drawer — not optional at this tier.

Finish:

• Conversion-varnish (CV) or 2K polyurethane sprayed in-shop, fully cured before delivery. Moisture-impermeable and chemical-resistant.
• Avoid: Latex paint, oil-based site-painted finishes (yellow within 5 years in bathrooms with no natural light), nitrocellulose lacquer (not moisture-rated).

Vanity Size & Layout Guide

Floating (wall-hung) vs freestanding:

• Floating vanities require structural blocking installed between wall studs during framing stage (2×8 or 2×10 horizontal blocking spanning at least 3 studs, screwed and glued). Weight capacity 200–400 lb depending on blocking spec. Modern contemporary look. Easier floor cleaning underneath.
• Freestanding (toe-kick base) vanities are the traditional approach. Lower install cost, no wall structural concerns. Classic / transitional / heritage look.

Single vs double sink: Going from single to double requires extending supply and drain lines through the vanity cabinet — adds $1,200–$2,800 in plumbing labour (306A plumber). Plan ahead at rough-in stage if going custom.

Countertop Pairing

Caesarstone vs Cambria vs Silestone:

• Caesarstone (Israel) — Industry leader, broadest pattern range. Statuario Maximus and Calacatta Nuvo are the marble-look workhorses. 10-yr warranty.
• Cambria (USA) — American-made, no global supply-chain volatility. Brittanicca and Whitehall are top-tier marble-look. Lifetime limited warranty.
• Silestone (Spain) — Cosentino-made, strong colour range. Calacatta Gold and Eternal Calacatta are top sellers. 25-yr warranty.

For most premium Toronto vanity tops we install Caesarstone Statuario Maximus or Cambria Brittanicca — both render marble-look quartz that the average viewer cannot distinguish from real Calacatta marble.

Sink & Faucet Pairing

Undermount (mounted from below the counter): Cleanest look. Counter material cleanup easier (sweep into sink). Standard for premium tier. Requires counter rated for undermount mounting (every premium quartz is rated for this; some natural stones need additional support).

Drop-in (top-mount, with rim sitting on counter): Acceptable on stock vanities; uncommon on premium custom. Easier install but visible rim collects soap and grime.

Vessel (sink sits on top of counter): Premium contemporary. Requires special wall-mount or tall deck-mount faucet ($400–$1,200). Sink heights 18"–22" — taller than standard, so vanity base must be 30"–32" instead of standard 34"–36" to keep ergonomic sink-rim height.

Integrated (sink molded as part of counter): Available in solid surface (Corian, Krion), cultured marble, concrete, and some engineered quartz programs. Seamless. Top tier of clean look.

Faucet hole spacing:

• Single-hole: Standard for contemporary, vessel faucets, wall-mount.
• 4" centerset: Three-piece widespread on 4" centers (handles + spout in one piece). Traditional bathroom standard.
• 8" widespread: Premium standard. Two handles and spout on independent escutcheons.
• Wall-mount: Plumbing comes through the wall behind the vanity, not through the deck. Premium contemporary look. Requires plumbing rough-in at the framing stage.

Premium brand pairings: Brizo Litze, Kohler Purist, Grohe Atrio (8" widespread or wall-mount), Graff Sade, Watermark Loft.

Toronto Custom Millwork Shop Sources

We work with established Toronto-area shops based on project tier and aesthetic:

• Aya Kitchens & Baths (Toronto) — Strong semi-custom program, broad door style selection, ~6-week lead. Mid-premium tier.
• Florentine Kitchens (North York) — Fully custom, traditional Shaker / inset / overlay specialist. Top-tier traditional finishes.
• Ariel Builders (multiple GTA locations) — Custom millwork with strong contemporary portfolio. 8–10 week lead.
• Tailored Living (Mississauga/GTA) — Specialty in built-in storage and integrated linen towers.
• Cabico (Quebec) — Cabinet manufacturer with strong GTA dealer network. Semi-custom with extensive finish options.
• Bellmont Cabinets (USA) — Premium imported semi-custom. Long lead but precise execution.

For European luxury (Antonio Lupi, Boffi, Falper, Porcelanosa Gamadecor), we coordinate through downtown Toronto showrooms.

Plumbing Rough-In Tolerance for Custom Vanity

Custom-built vanities are precise to 1/16". Existing wall openings rarely are. The five rough-in tolerances we verify before fabrication starts:

• P-trap height from finished floor: Standard 18"–20" for vanity-mounted drain.
• Supply line height: 21"–23" standard.
• Supply line horizontal spacing: 4"–8" depending on faucet centerset.
• Wall plumbness: Premium custom needs walls within 1/4" plumb over 8' run. Out-of-plumb walls get sistered/shimmed before installation.
• Floor flatness: Premium vanity bases need floor flat to 1/8" over the vanity footprint. Self-levelling underlayment may be required.

We measure all 5 tolerances at the pre-fabrication site visit. Adjustments made before fabrication is far cheaper than scribing solid-wood doors on install day.

Compliance & Code

• OBC 9.29.10: Waterproofing under any wet-zone wall (back wall of vanity if part of shower run).
• OBC 9.32.3: Ventilation requirement for bathroom — vanity install doesn't affect, but cabinet position relative to vent fan exhaust point may.
• OESC 26.700–26.726: Wet-zone GFCI requirements for any drawer-interior outlets, USB-C ports, integrated mirror defoggers, or under-cabinet lighting.
• Reg 169/03 / NSF/ANSI 372: Lead-free compliance on supply lines and any in-line valves (manifold, shutoffs).
• Custom millwork is not regulated by provincial trade licensing (it's finish carpentry, not plumbing/electrical), but plumbing and electrical sub-trades for vanity hookup ARE licensed work (306A, 309A).

FAQ (14 items)

1. Why are custom millwork bathroom cabinets so much more expensive than IKEA or Home Depot vanities? Box construction (hardwood plywood vs particleboard), drawer construction (dovetailed solid wood vs stapled MDF), hinges and slides (Blum/Salice lifetime vs generic), finish (in-shop sprayed CV vs site-painted MDF), and exact-fit measurement (every install custom-scribed vs box-standard sizes). Lifespan: 25+ years for custom vs 7–12 for stock.

1. What's the lead time on a fully custom vanity in Toronto? 6–10 weeks from sign-off on shop drawings. Imported European programs (Boffi, Antonio Lupi) 10–16 weeks. We schedule construction around the delivery date, so demo doesn't happen until the vanity is en route.

1. Can you match an existing wood tone in my home? Yes — that's a core competency of custom millwork. We bring stain samples to your home for finalization. Painted-finish matches are exact (any colour). Stained-wood matches are within 1 grade (perfect 100% matches across different wood species and grain isn't physically possible).

1. Floating vanity vs freestanding — which is better? Aesthetic preference + budget. Floating is contemporary, has higher install cost (wall blocking required in framing stage), needs structural verification. Freestanding has lower cost, classic look, no structural concerns. Both are equally functional.

1. What's the weight capacity of a wall-hung floating vanity? With proper blocking (2×8 or 2×10 horizontal blocking between studs, spanning minimum 3 studs, screwed and glued), wall-hung vanities support 250–400 lb. Plenty for the cabinet, quartz top, undermount sink, and daily use.

1. Should I get a single sink or double sink in my ensuite? Two adults sharing a morning routine: double sink justifies the cost premium ($1,200–$2,800 plumbing extension + larger vanity). One adult or shared single-sink workflow: single is fine, use the saved width for more storage.

1. What's the difference between semi-custom and fully custom? Semi-custom: pre-engineered box/door styles with custom sizing and finish (Aya, Cabico). 4–6 week lead. ~$5–$15K range. Fully custom: every dimension and detail made-to-order by a cabinetmaker (Florentine, Ariel). 6–10 week lead. ~$12–$32K range.

1. Can you integrate outlets into drawer interiors? Yes — 309A electrician (ECRA/ESA) wires GFCI-protected outlets and USB-C ports into drawer interiors during electrical rough-in. Common for hair-dryer and electric-toothbrush storage. $480–$900 per drawer location.

1. Quartz vs marble for the vanity top? Quartz (engineered, like Caesarstone or Cambria) is non-porous, no sealing, marble-look options indistinguishable from real marble at 90% of viewers' first glance. Marble (real) etches from acidic products (citrus, wine, some skincare), develops patina over years, requires sealing. For most premium Toronto vanities we install Caesarstone Statuario Maximus.

1. What's a medicine cabinet defogger and is it worth it? A heating element behind the mirror surface that prevents condensation after a shower. ~$280–$480 added. Worth it for daily-use ensuites. Skip in powder rooms.

1. Do you do the install or just supply? Both. Custom vanity supply + RenoHouse install is the integrated package. We can also install a vanity ordered through your own designer or custom shop — common for clients who want a specific cabinetmaker but RenoHouse for project management.

1. Will custom millwork survive humidity better than stock? Yes, dramatically. Hardwood plywood box construction with CV finish on all 6 sides of all components resists humidity for 30+ years. Particleboard or MDF box construction (stock vanity standard) shows visible bottom-corner swelling at year 7–10 in most ensuites.

1. Can I claim the Home Accessibility Tax Credit (HATC) on a custom vanity? Only on accessibility-specific features — open-knee section for seated user, lever handles, lower counter height (32" vs standard 34"–36"), accessible drawer pulls. Standard luxury custom millwork doesn't qualify. RenoHouse itemizes invoices to separate eligible spend.

1. What's the warranty? Custom cabinetmaker warranty on the cabinet (typically 5-yr finish, lifetime construction). Manufacturer warranty on hardware (Blum/Salice lifetime). Quartz top warranty (10-yr Caesarstone, lifetime Cambria). RenoHouse 2-year workmanship warranty on the install.
