How Much Does a Fiberglass Pool Cost in Maryland?

Fiberglass pool cost in Maryland depends on more than just pool size. It’s shaped by everything from Chesapeake Bay shoreline conditions to suburban zoning rules outside Washington, D.C. Whether installing in the gently sloped lots of Howard County, the sandy soils of the Eastern Shore, or the dense neighborhoods around Silver Spring, understanding Maryland’s unique mix of local factors is essential for building your backyard oasis.

From Annapolis to Hagerstown and across the state, Maryland homeowners face excavation, access, and installation variables based on soil conditions, municipal codes, or design decisions. Features like pool heaters, automated safety covers, or premium decking and landscaping are popular upgrades that help stretch the swim season and enhance enjoyment, but can significantly impact your final price tag. A local Thursday Pools dealer can help ensure your vision aligns with your lifestyle and budget.

Average Cost of Popular Pool Models Installed in Maryland

ASPEN (12’ x 25’)

The compact and classic Aspen is perfect for Maryland homeowners making the most of smaller backyard spaces, from historic row homes in Annapolis to cozy cul-de-sacs in Columbia. The pool’s design includes a built-in tanning ledge, wide entry steps, and an open swim area balancing style with practicality.

CATHEDRAL (14’ x 33’)

The Cathedral combines traditional aesthetics with thoughtful amenities, making it a natural fit for mid-size yards across Towson, Bethesda, or Ellicott City. The Cathedral has grand entry steps, ample bench seating, and a generous swim lane, providing a well-rounded space for both lounging and activity. It’s ideal for Marylanders who appreciate timeless elegance but want room to float, splash, and enjoy the outdoors.

 

Our survey of Maryland dealers shows the average cost for a standard installation of the Cathedral and medium fiberglass pool models, between 26 and 34 feet long or 400 to 600 square feet, is $85,000.

From Rock to Ridge: How Maryland’s Landscape Shapes Your Pool Installation

Maryland’s diverse terrain can make a big difference in your fiberglass pool installation—and what it ultimately costs. In western parts of the state, rocky soil may require heavy-duty excavation equipment and extended digging time. Along the Eastern Shore, looser and sandy soil near Cambridge or Ocean City often requires reinforcement to stabilize the pool shell and prevent shifting over time. Dense clay deposits in areas such as Anne Arundel or Prince George’s County can hold water, sometimes requiring added drainage solutions to protect your pool’s structure.

 

Topography plays its part, too. Rolling lots near Ellicott City or sloped landscapes in parts of Montgomery County may need extra grading or retaining walls to ensure a stable and level base for your pool and patio.

 

Backyard accessibility is another key factor. Tight lot lines, fencing, or overhead obstructions in historic neighborhoods like Annapolis or denser developments in Silver Spring or Towson may require alternative delivery methods or crane service to maneuver your fiberglass pool shell into place. These logistical details and adjustments can add time and costs to your project budget, but are essential for a secure installation and long-term performance.

 

AVERAGE ADDITIONAL YARD-RELATED EXPENSES IN MARYLAND
Excavating Sandy Soil	$1,000
Excavating Clay Soil	$900
Excavating Rocky Soil	$600
Above-Average Slope Requiring Extra Grading	$2,400
Limited Yard Access	$5,100

 

Fortunately, local independent Thursday Pools dealers know how to navigate Maryland’s varied conditions. They’ll evaluate your yard from the start—soil type, slope, and access included—so you can budget wisely and confidently.

 

Maryland’s Pool Barrier Requirements: What Homeowners Need to Know

Understanding the state’s safety regulations is crucial when planning a fiberglass pool installation in Maryland. The state follows the International Swimming Pool and Spa Code (ISPSC) with amendments, forming the Maryland Swimming Pool and Spa Code. This code mandates enclosing any residential pools deeper than 24 inches with a barrier at least 48 inches high. There are also specific requirements for gate functionality and fencing material spacing to prevent unauthorized access.

 

Many local jurisdictions, however, impose additional and stricter standards. Montgomery County, for example, requires securely anchored pool enclosures at least 5 feet tall. Gates must be self-closing and self-latching, with latches at least 4 feet above ground.

 

Anne Arundel County maintains the 4-foot minimum height and specifies that gaps under the fence cannot exceed 2 inches, while openings between pickets must be no more than 4 inches wide. Harford County adds that the barrier must be at least 20 inches from the pool’s edge, while Carroll County requires temporary safety fencing during construction and the filing of a pool enclosure affidavit before adding water to the pool.

 

Given these variations, consulting with your local municipality or a knowledgeable Thursday Pools dealer is essential to ensure compliance with all applicable regulations. Proper planning will help avoid unexpected costs and provide a smooth installation process.

 

According to our 2025 survey of Maryland dealers, the average cost for a 300-linear-foot pool fence is approximately $15,600.
