Choosing the Right Pool Shape for Your Southeast Michigan Backyard

April 22, 2026 · 5 min read · By Anderson Brothers Pools

The most common pool-shape mistake we see is the same one we’d make ourselves if we shopped on Pinterest first: falling in love with a shape that looks great in a magazine and then forcing it into a yard it doesn’t fit. The right pool shape isn’t the one with the most likes on Instagram — it’s the one that makes sense for your specific lot, your home’s architecture, your sun exposure, and how your family is actually going to use the pool.

Here’s how we think through pool shape during a custom gunite design conversation.

Start with the yard, not the inspiration board

Before shape gets discussed, we look at five things on your property:

  • Buildable footprint — setbacks from property lines, the home, and any easements. This often dictates the maximum dimensions.
  • Existing trees and landscape — what stays, what we work around, what comes out.
  • Sun exposure — where it’s sunniest from 11 a.m. to 5 p.m. is where the pool should go if you have a choice.
  • Sight lines — what you see from the kitchen, the family room, the deck.
  • Access — how kids and adults get from the back door to the pool, and from the pool to the bathroom.

The shape conversation comes after that. Now let’s get into the shapes themselves.

Rectangular: classic, formal, lap-friendly

The rectangle is the most popular shape we build, for good reason. It pairs cleanly with traditional and contemporary architecture, makes lap-swimming an option, and is the easiest shape to fit with an automatic safety cover. The geometry also tends to be the most cost-efficient per square foot of swim area.

Where rectangles excel:

  • Newer homes with strong rectilinear architecture (modern, transitional, contemporary)
  • Lots where setbacks and yard shape are themselves rectangular
  • Households that want the option of lap swimming as a workout
  • Anyone who wants an automatic safety cover (covers integrate cleanly with rectangles)

Where they’re less ideal: heavily wooded lots where curves would weave between trees better, or backyards where a rectangular pool would feel like a big concrete slab in an organic landscape.

Freeform: organic curves, naturalistic landscaping

A freeform pool follows curves rather than straight lines. It can look like a natural pond, lake inlet, or grotto, especially when paired with rock waterfalls, planted edges, and natural-stone decking. Freeform shells are the most flexible — we can integrate sun shelves, beach entries, and irregular depth profiles much more naturally than in a rectangle.

Freeform works best when:

  • The home leans rustic, craftsman, lake-house, or otherwise organic
  • The lot has mature trees, slope, or natural topography we want the pool to sit inside (not stand against)
  • You want the pool to feel like part of the landscape rather than a feature dropped on top
  • You’re planning a larger backyard build with natural-stone decking and planted transitions

Roman / Grecian: rounded ends, traditional feel

A Roman pool has rounded semi-circular ends on a rectangular center; a Grecian has cut corners (chamfered angles) instead of curves. Both pair beautifully with traditional architecture — Tudor, Colonial, French Country — and read as more formal and intentional than a plain rectangle without going full freeform.

This is a popular shape in Bloomfield Hills, parts of Birmingham, and the more traditional Troy and Rochester subdivisions, where the home’s architecture is doing a lot of work and the pool wants to complement rather than compete.

L-shape and T-shape: separate the diving area, define a play area

An L-shape (or “kidney with a leg”) gives you two distinct use zones — a deeper diving end and a separate shallow play area — without making the pool feel chopped up. T-shapes do something similar with the deep end as the cross-bar.

These shapes work well in households with a wide mix of swimmer ages, where having a clear “shallow side for the kids” is genuinely useful. They take more thought on coping and decking transitions to look intentional rather than awkward, but done well they’re some of the most usable family pools we build.

Custom one-of-a-kind shapes

Custom gunite is, well, custom. Some of our most interesting projects don’t fit any of the categories above:

  • Vanishing-edge pools that read as merging with a lake or a hillside view
  • Beach-entry pools with zero-depth gradual entries
  • Pools with integrated raised spas, swim-up bars, sun shelves with bubbler jets
  • Geometric modern pools with sharp corners, integrated planters, or vanishing-edge troughs that feed water features

If you’ve seen something specific you love, bring the photo to the consultation. Most of the time, “can we do this in our yard?” has a longer and more interesting answer than yes or no — we’ll talk through what would have to be true to make it work.

How home architecture should influence shape

A quick rule of thumb that holds about 80% of the time:

Home style Pool shapes that pair well
Tudor, Colonial, French Country Roman, Grecian, formal rectangle with raised spa
Modern / contemporary Rectangle, geometric, vanishing edge
Craftsman, lake-house, rustic Freeform, beach entry, integrated waterfall
Mid-century / ranch Rectangle or kidney (period-correct)
Transitional / mixed Almost any — let yard and use case decide

The single best piece of shape advice

Spend the design conversation talking about how you’ll actually use the pool, not what shape you want. Are kids the primary users? Adults entertaining? Do you want a quiet evening soak in a spa? Do you swim laps? Will the pool host pool parties or be more for the immediate family?

Once we know how it’ll get used, the right shape is usually obvious to both of us by the end of the conversation. That conversation is free.

Frequently asked questions

What’s the most popular pool shape in Southeast Michigan?

Rectangular is by a wide margin the most common new build, followed by freeform, then Roman / Grecian, then L-shape. Custom shapes account for a smaller but growing share, especially on larger Bloomfield Hills, West Bloomfield, and Rochester Hills lots.

Do certain pool shapes cost more than others?

Per square foot, rectangles are typically the most cost-efficient. Freeform pools cost slightly more for the same swim area because of the curved coping and more complex steel cage. Custom shapes with vanishing edges, beach entries, or integrated raised features cost meaningfully more.

Can I add a spa to any pool shape?

Yes. Spas integrate cleanly into rectangles (often as a raised spillover spa at one end), L-shapes (in the corner), Roman pools (centered on one end), and freeform pools (tucked into a curve). The spa shape is independent of the pool shape.

What pool shape works best with an automatic cover?

Rectangles, by far. The cover tracks fit straight runs cleanly. Roman and Grecian pools can work with covers if planned at design stage. Freeform pools generally don’t accommodate automatic covers; safety alternatives include alarms, fences, and manual covers.
