How to Put Quartz Countertop Over Washer Dryer

Installing a quartz countertop over your washer and dryer is a great way to create a built-in look in your laundry room. Quartz is an engineered stone that is durable, stain-resistant, and easy to clean, making it an ideal material for high-use areas like laundry rooms. Here is a step-by-step guide on how to put a quartz countertop over your washer and dryer.

Selecting the Right Quartz Slab

When selecting a quartz slab for your washer and dryer countertop, keep the following in mind:

  • Thickness – Aim for at least 2cm (3/4″) thickness for durability and stability. Thinner slabs may crack under the weight of laundry loads.
  • Overhang – Allow for a 10-15cm overhang on the front and sides to create a built-in look. This will also give you space for folding clothes.
  • Edge profile – A standard squared edge is the most affordable option. For a more high-end look, choose an ogee, bevel, or other edge profile.
  • Color/pattern – Choose a neutral quartz color and pattern that will resist showing stains and dirt. Whites, grays, and blacks are ideal laundry room options.
  • Size – Measure the total length and depth you need to cover your washer and dryer. Leave an extra 5-10cm on each side for adjustments.

Preparing the Base

The base underneath your quartz countertop needs to be extremely sturdy to support the weight. Here are some tips:

  • Remove existing countertops, taking care not to damage the base cabinets.
  • Inspect base cabinets for levelness and stability. Shims or braces may be needed.
  • Build up the substrate with 3/4″ exterior grade plywood cut exactly to size.
  • The plywood should be moisture-resistant and free of knots. Screw it securely into the base units.

Installing the Quartz Countertop

Step 1 – Set the quartz slab in place on top of the plywood and check that it fits correctly. Mark the overhangs with a pencil.

Step 2 – Lift the slab and apply a thin layer of silicone adhesive to the plywood.

Step 3 – Carefully set the quartz slab back in place, aligning with the overhang lines.

Step 4 – Use a level to double-check for flatness. Insert shims as needed until the slab is completely level.

Step 5 – Allow the adhesive to cure for 24 hours before proceeding. The quartz should now be firmly attached to the base.

Step 6 – Use a pencil to trace the outlines of your washer and dryer onto the slab. Remove the appliances and set aside.

Step 7 – Following the outlines, use a jigsaw with a diamond grit blade to cut holes for your washer and dryer. Make rounded inner corners to prevent cracking.

Step 8 – Carefully lift the cut quartz slab off and set aside. Vacuum dust from the plywood substrate.

Step 9 – Apply a thin layer of silicone adhesive around the edges of the appliance holes.

Step 10 – Set your washer and dryer back in place, dropping them gently into the cutouts.

Step 11 – Apply another layer of adhesive to the plywood around the appliances.

Step 12 – Set the quartz slab back onto the base, allowing it to settle around the washer and dryer.

Step 13 – Allow the adhesive to fully cure for at least 24 hours before use.

Step 14 – Seal all edges with clear silicone caulk to prevent moisture intrusion.

Finishing Touches

Once fully installed, add any final touches:

  • Use silicone caulk to fill any gaps between the quartz and walls.
  • Apply caulk where the quartz slab meets the washer and dryer to prevent rattling.
  • If desired, install matching quartz backsplash tiles using thinset adhesive.
  • Consider adding coordinating quartz shelves, hooks, and other laundry room accessories.

With proper planning, preparation, and installation, a quartz countertop can create a stylish and functional built-in look for your laundry room. Take your time and don’t rush the process – the finished results will be well worth it.

Frequently Asked Questions

How thick does the plywood substrate need to be under the quartz?

3/4″ (19mm) exterior grade plywood is recommended as the minimum thickness for a stable base. Go thicker if possible or double up layers for extra strength.

What edge profile should I choose for the quartz overhang?

An eased or pencil edge is the most affordable and low-maintenance option. Beveled and ogee edges create a more high-end look if desired.

Should I seal the seam between the quartz and washer/dryer?

Yes, use a silicone caulk to fill any gaps or crevices between the appliances and quartz. This prevents rattling and debris buildup.

Can I install a matching quartz backsplash too?

Absolutely! Adhere quartz backsplash tiles to the wall using thinset mortar. Use silicone caulk where the backsplash meets the countertop.

How often do I need to seal the quartz countertop?

Quartz is non-porous and unlikely to stain, so sealing is not necessary. Simply clean spills promptly and sanitize regularly. Reseal edges yearly.

Can I cut the sink hole myself or do I need a pro?

Cutting the sink hole requires specialized tools and experience. Hire a fabricator to custom cut the hole to ensure proper fit and prevent cracking.
