How to Include Laundry in Your Bathroom Remodel: Design Considerations

Combining laundry facilities with your bathroom can be a smart space-saving solution, especially in smaller homes or apartments. This dual-purpose approach requires careful planning to address plumbing, electrical, ventilation, and moisture control challenges. Understanding the essential design considerations, from appliance positioning to flooring choices, helps ensure your bathroom-laundry combination functions efficiently while maintaining comfort and safety for daily use.

Essential Plumbing and Electrical Updates for Bathroom Laundry Combinations

Integrating laundry appliances into your bathroom requires significant plumbing and electrical modifications. Your contractor must install dedicated water supply lines for the washing machine, typically requiring hot and cold water connections with shut-off valves. The drainage system needs a standpipe or floor drain capable of handling the washer’s discharge volume, which can reach 40-50 gallons per cycle.

Electrical updates include installing GFCI-protected outlets for laundry appliances, positioned away from water sources according to Canadian electrical codes. Dryer installations require 240-volt outlets for electric models or proper ventilation ducting for gas units. Professional contractors must ensure all electrical work meets CSA standards and local building codes.

Maximizing Small Bathroom Space: Stackable Washer Dryer Options and Ventilation Requirements

Stackable washer-dryer units offer the most space-efficient solution for bathroom laundry integration. These compact appliances typically measure 24-27 inches wide, fitting into closet-sized spaces while providing full washing and drying capabilities. Front-loading models work best for stacking configurations and offer superior water efficiency.

Ventilation becomes critical when installing dryers in bathroom spaces. Proper exhaust ducting must direct moisture and heat outside, preventing humidity buildup that could damage bathroom fixtures and promote mold growth. Bathroom exhaust fans should be upgraded to handle the additional moisture load, with capacity ratings of at least 150 CFM for combined bathroom-laundry spaces.

Bathroom Laundry Room Design: Understanding Moisture Control and Flooring Choices

Moisture control represents the primary challenge in bathroom-laundry combinations. Installing vapor barriers behind washing machines prevents water damage to walls, while proper caulking around appliances creates watertight seals. Dehumidification systems may be necessary in humid climates or poorly ventilated spaces.

Flooring choices must withstand constant moisture exposure and potential water spills. Ceramic or porcelain tiles provide excellent water resistance and durability. Luxury vinyl plank flooring offers a softer alternative with good moisture protection. Avoid laminate or hardwood flooring in these applications, as they can warp or deteriorate when exposed to washing machine leaks or bathroom humidity.

Comparing Bathroom Remodel Configurations: Where to Position Laundry Appliances

Appliance positioning significantly impacts functionality and accessibility. Corner installations maximize floor space while keeping appliances away from high-traffic areas. Closet conversions work well when existing bathroom closets can accommodate plumbing and electrical requirements.

Against-the-wall configurations provide easy access for loading and maintenance while maintaining clear bathroom pathways. Alcove installations create dedicated laundry zones within larger bathrooms, often incorporating custom cabinetry for storage. Consider door swing patterns and clearance requirements when positioning appliances to ensure comfortable use of both bathroom and laundry functions.


Configuration Type Space Requirements Installation Complexity Cost Estimation
Corner Installation 5x5 feet minimum Moderate $3,500-$6,000
Closet Conversion 3x6 feet minimum High $4,000-$7,500
Wall-Mounted Stack 3x3 feet minimum Moderate $3,000-$5,500
Alcove Integration 4x6 feet minimum High $5,000-$9,000

Design Elements That Enhance Bathroom-Laundry Functionality

Storage solutions become essential in combined spaces. Built-in cabinets above appliances provide detergent and supply storage while maintaining clean lines. Pull-out drawers beneath countertops offer convenient access to laundry supplies without cluttering bathroom surfaces.

Lighting design should address both bathroom and laundry needs. Task lighting over appliances improves visibility for sorting and loading clothes, while ambient lighting maintains bathroom comfort. Motion-sensor switches provide hands-free operation when carrying laundry loads.

Privacy considerations include sound dampening materials to reduce appliance noise during operation. Insulation behind appliances minimizes vibration transfer to adjacent rooms. Pocket doors or sliding panels can separate laundry areas from bathroom spaces when needed.

Successful bathroom-laundry integration requires balancing functionality with aesthetics. Choosing appliances that complement bathroom fixtures creates visual cohesion, while strategic placement ensures both spaces remain comfortable and efficient. Professional planning and installation ensure code compliance and optimal performance for years to come.
