When considering fiberglass pool cost in Michigan, it’s important to factor in more than just the pool shell and installation. Michigan’s climate, terrain, and local regulations shape a new pool project’s final price tag. Homeowners across the Detroit metro area, Traverse City, Grand Rapids, and Ann Arbor may face different challenges, from navigating sloped lakefront properties to maximizing smaller urban yards. The state’s long winters and shorter swim seasons also inspire many Michiganders to add features like pool heaters, automatic covers, or attached spas to extend usability in the spring and fall.
Varied soil conditions across the state—from sandy lakeshore lots to heavy-clay conditions inland—also affect excavation costs and site prep needs. Local zoning laws, permitting processes, and seasonal construction windows further influence timelines and budgets. Working with a Michigan-based fiberglass pool expert ensures your design fits your budget, lifestyle, and long-term expectations.

Average Cost of Popular Pool Models Installed In Michigan
ASPEN (12’ x 25’)
The Aspen‘s smallest footprint makes a strong case for space-savvy design, from compact lakeside retreats in Petoskey to backyard gems in suburban Grand Rapids. Its integrated tanning ledge offers the perfect perch for enjoying Michigan’s summer sun, while the open swim lane and easy-access steps cater to both relaxation and movement. Whether you’re looking to cool off after a workout or host friends for a casual evening dip, the Aspen delivers big functionality without requiring a sprawling yard.
Based on our 2025 survey of Thursday Pools independent dealers in Michigan, the average cost for a standard installation of the Aspen—or another small fiberglass pool design under 26 feet long and 400 square feet—is $76,000.
TITUS (14’ x 33’)
The Titus brings a calm and inviting presence to mid-size backyards across Michigan, from tree-lined neighborhoods of Kalamazoo to newer developments in Novi or Midland. Its flowing shape softens traditional yard layouts while offering plenty of built-in comfort zones, including wide entry steps, perimeter seating, and a full-length conversation bench. Ideal for swimming laps, floating under a summer sunset, or catching up with family over the weekend, the Titus carefully balances elegance and function.
According to our 2025 survey, the average cost for standard installation of the Titus or other mid-sized fiberglass pool designs between 26 and 34 feet long or 400 to 600 square feet is $120,000.
CATHEDRAL LX (16’ x 40’)
The Cathedral LX is ideal for Michigan’s larger properties, such as scenic acreage outside Traverse City or show-stopping backyard builds in Bloomfield Hills. Its formal design pairs traditional elegance with thoughtful, modern touches, including grand entry steps, a spacious tanning ledge, and an expansive swim lane with consistent depth. This large-format pool offers the flexibility to entertain, exercise, or simply unwind in style. Its shape adapts well to Michigan’s diverse landscapes, whether complementing natural woodlands or installing a full outdoor living space with pergolas, fire features, or a spa-ready setup.
Our dealer survey from 2025 shows that the average cost for a standard installation of the Cathedral LX—or other large fiberglass pool models over 35 feet long or more than 600 square feet—is $136,000.
Michigan Landscapes: What Lies Below the Surface Impacts Pool Costs
No two Michigan backyards are the same, and what’s under the grass can have just as much impact on your fiberglass pool project as what’s above it. From sandy soils along Lake Michigan to dense clay beds around Lansing and Flint, ground conditions influence everything from excavation methods to long-term pool stability. Clay-rich soil, for example, holds water and may call for enhanced drainage solutions to protect the pool structure. Conversely, looser sandy soil might require reinforced backfilling to keep everything firmly in place over time.
Then there’s the shape of the land itself. Sloping lots, common in areas like Grand Rapids or the hills around Traverse City, often need grading or retaining walls to create a level, secure base for the pool and patio. These structural additions add to the project scope, but help ensure safety, longevity, and smooth performance year after year.
Access also plays a critical role. Tighter lots in urban settings like Ann Arbor or older neighborhoods with mature trees and fencing can make it difficult to maneuver large installation equipment. In these cases, cranes or alternate delivery methods may be necessary, potentially adding to your overall investment.

Pool Fencing and Safety Requirements in Michigan: What Homeowners Should Know
Most of Michigan’s residential pool safety laws follow the International Swimming Pool and Spa Code (ISPSC) standards. Generally, homeowners and installers must surround any pool deeper than 24 inches with a barrier at least 48 inches tall using self-closing, self-latching gates. Latches should be at least 54 inches off the ground or on the pool-facing side to reduce the risk of unsupervised access.
Beyond this standard framework, local municipalities often introduce their own specific rules and regulations. The differences can significantly impact your installation timeline and costs.
Norton Shores, for example, outlines clear fencing rules and setback requirements while recommending safety covers for additional protection. Eaton County, meanwhile, enforces its own fencing rules and requires a full site plan that includes the layout of the pool barrier, gate location, setbacks, and electrical inspections. The city of Farmington Hills has detailed barrier design regulations that prohibit climbable surfaces and require pool equipment screening. Milan emphasizes the need for both permanent and temporary fencing, even during the construction phase, while Fraser’s local code includes specific setback requirements and barrier placement and rules about screening visible pool equipment from adjacent properties.
Because regulations vary widely between cities and townships, it’s crucial to consult your local codes early in your planning process. A trusted local Thursday Pools dealer familiar with Michigan’s diverse municipal rules can help you prepare the right documentation, navigate permits, and ensure your pool is safe, secure, and compliant.
According to our 2025 survey of independent Thursday Pools dealers in Michigan, the average cost for a 300-linear-foot pool fence is approximately $5,067.
