Designing in Perth and across WA means planning for heat, UV, sea breeze and the odd summer downpour. If you’re comparing a waterproof cabinet for an alfresco kitchen, a moisture‑resistant vanity, or a durable outdoor wardrobe, here’s a practical guide to materials, styles, costs and the renovation process—tailored to Australian conditions.
Why waterproof and weatherproof cabinets matter in WA
Perth’s high UV, coastal salt air and temperature swings are tough on cabinetry. Inside, steam from dishwashers and laundries can swell boards. Outside, rain, sun and wind will quickly punish the wrong substrate or finish. Choosing the right waterproof cabinet construction gives you longer life, less maintenance and lower total cost of ownership.
- Outdoor kitchens: choose weatherproof outdoor cabinets and benchtops designed for UV and heat.
- Bathrooms and laundries: specify moisture‑resistant (HMR) boards, sealed edges and quality hardware for a reliable waterproof kitchen or laundry fit‑out.
- Wardrobes: for an outdoor wardrobe or enclosed balcony, use materials rated for exterior exposure.
Quick definition: Waterproof vs Weatherproof
Waterproof cabinet usually means the box material resists liquid ingress for prolonged exposure. Weatherproof cabinet means the entire unit withstands rain, UV and temperature changes outdoors. Not all waterproof materials are UV‑stable, so outdoor use needs both.
Quick definition: IP ratings (AS/NZS 60529)
IP ratings classify protection against dust and water for electrical items. If you’re adding lighting or power to alfresco cabinetry, select fittings with appropriate IP ratings and engage a licensed electrician.

Our design and renovation process
- Consultation and measure – We visit your home anywhere across Perth to assess exposure (sun, rain, wind), services, and appliance sizing common in Australia (e.g., 900 mm cooktops, bar fridges).
- Design – Concepts for alfresco kitchens, bathrooms, laundries or wardrobes with space planning, storage and compliance notes (e.g., wet area waterproofing to AS 3740 by your builder or tiler).
- Material selection – We specify substrates and finishes for indoor moisture or outdoor weather, including hardware like stainless or coated hinges.
- WA‑made fabrication – Custom cabinetry WA made for your site. Soft‑close drawers, Blum or Hettich hardware, and sealed edges as standard.
- Installation and finishing – Coordination with licensed trades for plumbing and electrical in line with local regulations.
- Aftercare – Cleaning and maintenance guidance for long life, especially in coastal locations.
Quick definition: HMR board
HMR (High Moisture Resistant) particleboard or MDF is formulated to resist swelling from humidity and minor spills. It’s ideal for indoor wet areas when properly sealed, but it isn’t a substitute for exterior‑grade materials outdoors.
Best materials and finishes for indoor and outdoor use
Outdoor alfresco: weatherproof outdoor kitchen cabinets
- Aluminium-framed carcasses with composite or compact laminate panels: light, corrosion‑resistant and stable in heat.
- Compact laminate (exterior‑grade): dense, water‑impervious, UV‑stable. Excellent for doors and panels.
- HDPE/PVC board cabinetry: fully waterproof outdoor cabinet option, easy to clean; best with bracing to limit thermal movement.
- Marine‑grade ply with 2‑pack marine coatings: premium look but requires maintenance; seal edges meticulously.
- Hardware: stainless steel or coated hinges and runners; soft‑close drawers rated for exterior use.
- Benchtops: porcelain/sintered stone (e.g., Dekton), granite, or stainless steel. Note many engineered stone brands aren’t warranted outdoors.
Indoor wet areas: kitchens, bathrooms and laundries
- HMR MDF/particleboard carcasses with fully sealed edges and moisture‑tolerant adhesives.
- 2‑pack polyurethane doors or high‑pressure laminate with ABS edges for durability.
- Veneer or solid timber is possible with correct sealing and ventilation away from direct, constant moisture.
- Hardware: quality soft‑close runners and hinges (e.g., Blum) for long life in steamy rooms.
Engineered Stone vs Laminate: where each shines
For benchtops, especially around sinks and dishwashers, water and heat resistance are key. Outdoors, lean to porcelain or stainless.
| Property | Engineered Stone Benchtop | High-Pressure Laminate Benchtop |
|---|---|---|
| Water resistance | Excellent | Very good with sealed joins |
| Heat/UV suitability outdoors | Often not warranted outdoors; UV can yellow | Not suitable outdoors; UV/heat can degrade |
| Indoor durability | High impact and stain resistance | Good everyday performance; avoid direct heat |
| Price (indicative) | $$$ | $$ |
| Best use | Indoor kitchens, sculleries, butler’s pantry | Indoor kitchens, laundries, rentals |
For alfresco areas in WA, we typically specify porcelain benchtops or stainless steel to handle UV and heat near BBQs.
Notes for coastal homes and heat
- Salt air accelerates corrosion—choose marine‑grade hardware and rinse surfaces occasionally.
- High summer heat calls for UV‑stable finishes; avoid dark gloss outside where possible due to heat absorption.
- Allow ventilation gaps for bar fridges and smokers; Australian appliances often require 50–100 mm airflow clearances.
Layouts and styles that work
Outdoor layouts
- Straight runs or L‑shapes under cover, with sink and prep near the BBQ.
- Island carts on casters for flexible entertaining.
- Integrated appliances: bar fridge, bin drawers, concealed gas bottle bay.
Indoor layouts
- U‑shape or galley kitchens with a well‑ventilated scullery or butler’s pantry.
- European laundries with stacked washer/dryer and drip‑dry rails.
- Wardrobes with pull‑out shoe drawers, soft‑close runners and internal lighting.
Popular styles in Perth
- Shaker kitchen doors in 2‑pack with matte black tapware or brass handles.
- Hamptons style for coastal homes with V‑groove panels.
- Contemporary slab fronts, finger‑pull rails and porcelain splashbacks.
Case example: Cottesloe alfresco
A compact L‑shape using aluminium frames, compact laminate doors and a porcelain benchtop. Result: a weatherproof cabinet run that handles sea breeze and summer heat, with soft‑close drawers and a built‑in 900 mm BBQ.
Case example: Mount Lawley laundry
HMR carcasses, 2‑pack doors, ABS edges and a laminate benchtop with an under‑mount sink. Pull‑out hampers and tall storage keep humidity in check—ideal for busy families.

Practical checklist for your waterproof or weatherproof cabinet project
- Exposure: fully outdoors, semi‑covered, or enclosed?
- Substrate: exterior‑grade (aluminium/compact laminate/HDPE) or HMR for indoor wet areas?
- Edges and sealing: are all cut edges sealed and silicone detailed at wet junctions?
- Hardware: stainless or coated hinges/runners; soft‑close drawers rated for conditions.
- Benchtop: porcelain/granite/stainless for outdoors; engineered stone or laminate indoors.
- Ventilation: BBQ and fridge clearance; consider heat shields near burners.
- Drainage: falls and overhangs to shed water; kickboard material suitable for splashes.
- Compliance: wet area waterproofing to AS 3740; electrical IP ratings outdoors; licensed trades.
- Maintenance: cleaning schedule, UV protection, and hardware checks, especially near the coast.

FAQ
What is the best material for a waterproof cabinet outdoors in Perth?
The most reliable options are aluminium-framed carcasses with compact laminate doors, or HDPE/PVC board cabinetry. Pair them with porcelain or stainless steel benchtops. Marine-grade ply can work with meticulous sealing and regular maintenance.
Are waterproof kitchen cabinets truly waterproof or just water-resistant?
Indoors, most cabinets are moisture-resistant (HMR) rather than fully waterproof. Outdoors, look for exterior-rated materials like compact laminate or HDPE that are effectively waterproof and UV-stable, plus stainless or coated hardware.
How much do weatherproof outdoor kitchen cabinets cost in WA?
Expect from $6,500–$18,000+ for cabinetry on a small to mid-sized alfresco run, plus $3,500–$10,000 for porcelain or stainless benchtops. Full outdoor kitchens commonly total $20,000–$45,000+ installed, excluding appliances.
Can you retrofit existing outdoor wood cabinets to be weatherproof?
Often yes. We can add new weather-seals, replace doors with compact laminate, upgrade to stainless hardware and recoat exposed edges. Severely swollen or delaminated carcasses are usually more economical to replace.
What maintenance do waterproof outdoor cabinets require in coastal areas?
Rinse surfaces with fresh water periodically, check and lubricate hinges, re-silicone joints if gaps appear, and avoid abrasive cleaners. Keep BBQ heat and flames clear of doors and edges to prevent warping or discolouration.
