PARK WASHROOM Precast Concrete Washroom

CHIMNEY HEIGHTS PARK · SURREY, BC

A Precast Concrete Washroom Built for Public Use

Sanderson Concrete manufactured a custom precast concrete washroom building for the City of Surrey at Chimney Heights Park, combining accessibility, durability and secure service areas in a purpose-built public facility.

PROJECT OVERVIEW

Designed, Cast and Assembled Before Reaching the Site

Sanderson worked with UJM Architecture and the City of Surrey Parks, Recreation and Culture team to manufacture a new washroom building designed to provide functional wheelchair access and long-term performance in a busy public park.

The precast structure was cast and assembled at Sanderson Concrete's plant in two major stages. The lower building assembly included the exterior walls, interior walls and floor, while the upper assembly incorporated the roof and service-room components.

Accessible Public Facility

Designed to provide functional wheelchair access for park visitors and the surrounding community.

Secure Service Area

Interior panels separate the service room from the public-facing areas of the washroom.

Off-Site Precast Assembly

Major structural components were manufactured and assembled at Sanderson's facility before installation.

Behind the Build

From Precast Panels to a Complete Public Facility

This precast concrete washroom was assembled as a complete building system, bringing together structural panels, welded connections, mechanical services, durable fixtures and roof construction before final delivery.

The fabrication process allows major components to be coordinated in a controlled environment before the finished structure reaches the park.

01 Structural Assembly

Building the Precast Concrete Shell

Fabrication begins with individual precast concrete wall panels. Each panel is positioned and aligned to establish the shape, dimensions and primary enclosure of the washroom building.

02 Structural Connections

Bringing the Building Together

Once the wall panels are in position, embedded connections and fabrication details secure the individual precast pieces into a unified building shell.

03 Mechanical & Interior

Building Services Installed Before Delivery

Plumbing, mechanical systems and interior components are coordinated within the precast structure before the building leaves the manufacturing environment.

Dedicated mechanical service area
Heat-traced water lines for cold weather
Stainless steel public-use fixtures

Technical Details

Built for Demanding Public Environments

Material selection and building-system details support security, durability, maintenance and year-round operation.

01 Anti-Graffiti Exterior Finish

Sandstone precast wall panels are protected for demanding public-space applications.

02 Stainless Steel Components

Weld plates, gutter, sink, mirror and fixtures use durable materials.

03 Secure Service Room

Mechanical services are contained within a dedicated secure area.

04 Year-Round Operation

Insulation and heat-traced lines support operation through winter conditions.

05 Natural Light

A large skylight brings natural daylight into the precast enclosure.

06 Durable Interior Finish

Polished concrete and robust materials help reduce long-term maintenance.

Stage 04 / Building Enclosure

Final Roof Assembly

Roof construction completes the building enclosure and prepares the precast washroom for finishing, transportation and installation at the project site.

Stage 05 / Transportation

From the Plant to the Project Site

With the major precast, roof, mechanical and interior components already assembled, the building is prepared for transport to the project site.

Off-site fabrication allows a significant portion of the building work to be completed before the washroom arrives at the park.

More Work Completed Before Arrival

Precast fabrication, building assembly and integrated systems reduce the amount of construction that must occur directly within the park.

Stage 06 / Site Completion

Installed at Chimney Heights Park

Once delivered, the prefabricated washroom becomes part of the completed park environment. These views show the installed structure from several angles shortly after site work.

The exterior precast finish, roof enclosure, accessible entrance and service-area detailing are visible in the completed building.

Stage 07 / Completed Project

From Precast Components to a Finished Public Facility

The completed washroom demonstrates how off-site precast fabrication can become a durable architectural element within an active public park.

PROJECT TESTIMONIAL

What the City of Surrey Says

Feedback from the Surrey Parks team following the modular precast concrete washroom project.

SURREY PARKS · MODULAR PARK WASHROOM PROJECT

“It was a pleasure to have Sanderson Concrete as part of the Surrey Parks – Modular Park Washroom project team. Their contributions to the design detailing and development process were pivotal to the success of what proved to be a very complicated little building.

The creativity and skill of the Sanderson Concrete team was invaluable, as we surmounted numerous challenges and achieved an outstanding end product. We applaud Sanderson Concrete for their determination, team orientation, and professionalism throughout the project. Well Done!”

PRECAST WASHROOM FAQ

Planning a Precast Concrete Washroom?

Answers to common questions about precast concrete washroom buildings for parks, municipalities, recreation facilities and other public-use environments.

01 What is a precast concrete washroom?

A precast concrete washroom is a permanent public-use washroom building manufactured using precast concrete components. Major structural elements can be fabricated and assembled off-site before the building is transported to the project location.

02 Where are precast concrete washrooms typically used?

Precast washrooms can be used in municipal parks, recreation areas, public spaces, trail systems and other locations that require a durable permanent facility. The appropriate configuration depends on site conditions, servicing and project requirements.

03 Can the washroom layout be customized?

Project-specific layouts, dimensions, accessibility requirements, service areas, fixtures, finishes and other details can be reviewed during project development. Feasibility depends on the design and technical requirements of the specific washroom project.

04 Can accessibility features be incorporated into the design?

Yes. Accessibility requirements can be considered as part of the washroom layout and project review. The final design should be coordinated with the applicable project specifications, codes and accessibility requirements.

05 How much of the building can be completed off-site?

Depending on the project, precast wall assemblies, structural connections, mechanical components, plumbing, interior fixtures and roof components can be coordinated before the building reaches the site. This can reduce the amount of construction work required directly within the park or public space.

06 How is a precast washroom transported and installed?

After fabrication and assembly, the washroom components are prepared for transportation to the project site. Delivery, lifting, placement and final site connections must be coordinated around site access, equipment, foundations and the requirements of the specific project.

07 Can precast washrooms be designed for year-round use?

Year-round operation can be considered during project design. For example, the Surrey modular washroom project incorporated an insulated mechanical service area and heat tracing on water lines. Requirements vary by location, climate and servicing conditions.

08 What information should I provide when requesting a quote?

Helpful information includes the project location, intended application, preliminary dimensions, quantity, accessibility requirements, servicing information, drawings or specifications, finish requirements and desired project timeline.

Request Project Information

09 What is the difference between a full precast washroom and El Baño?

A custom precast washroom building can support more extensive layouts, servicing, mechanical systems and project-specific architectural requirements. El Baño is a simpler permanent precast concrete outhouse solution intended for applications such as parks, campgrounds, trails and remote public-use sites.
