Wood vs vinyl shutters: which is better, room by room

Updated October 17, 2026

The short answer: choose wood for every room where the shutter stays dry, which is nearly all of them. Choose vinyl for a window that gets wet, like one inside a shower. Everything below is the evidence.

What each one is

Vinyl shutters (also sold as PVC or polyvinyl shutters) are extruded plastic. Better ones have an aluminum stiffener inside: The Shutter Store describes its vinyl as “100% solid polyvinyl with aluminum core”^[1], and Hunter Douglas says the stiles, louvers and T-posts of its Palm Beach vinyl shutters are “reinforced with aluminum”^[2].

Wood shutters are made from a hardwood such as basswood or, in our case, American poplar. Purdue University describes yellow-poplar as relatively light, 29.4 pounds per cubic foot at 12% moisture, and says it “is easily painted and tends to hold paint well”^[5].

Heat and sun

Wood doesn’t soften in heat. Plastic can. Hunter Douglas, which sells vinyl shutters, says its Palm Beach shutters “are not recommended for skylight applications” and that if they are installed in a skylight, “warping of the frame and/or louvers may occur”^[2].

Norman, which sells wood and composite shutters but not PVC, goes further: it says prolonged high heat “may cause some PVC shutter components to bow, twist, expand, or distort” and that UV exposure can make some PVC “fade, discolor, or yellow”^[3]. Read that as a competitor’s argument, not a test result. The fair summary: on an ordinary window, a well-made vinyl shutter is fine; on a hot, sunny glass wall or a skylight, the vinyl makers themselves are cautious.

Water and humidity

This is where vinyl wins. The Shutter Store, which sells both, lists vinyl as waterproof and wood as not, and recommends vinyl for “Bathrooms, kitchens, and other humid areas”^[1].

Wood’s issue isn’t humidity as such, it’s liquid water. Indoors, wood takes on and gives off moisture with the seasons: the National Research Council of Canada puts wood in heated buildings at about “6% in winter to 12% in summer”^[6]. Paint slows that exchange; a painted shutter in a ventilated room moves a little and settles. A shutter that’s splashed every day is a different story, which is why we tell people to put vinyl in a shower window.

Weight and sagging

Sources disagree, and the reason is what’s inside. The Shutter Store lists wood as lighter and vinyl as heavier^[1]; Norman says PVC components “can become relatively heavy, especially when internal reinforcement is added”^[3]. Bloomin’ Blinds rates vinyl as light and wood as heavy^[4], and also notes that many composite shutters are “hollow or foam-filled”. A solid vinyl louver with an aluminum core and a hollow plastic one are very different things.

Weight matters on wide panels and doors, where hinges carry it. Hunter Douglas caps Palm Beach hinged panels at 36 inches wide and bifold panels at 24 inches^[2]. Whatever you buy, ask for the panel weight and the maximum panel width.

Fitting, repairs and colour

Wood forgives. It “can be gently sanded during installation to accommodate any variance in the window opening”, and it can be sanded and repainted if you change colour later^[1]. Vinyl can’t be sanded, and repainting it is “not recommended”^[1].

Colour is the other big difference. Hunter Douglas lists three colours for Palm Beach, all whites^[2]. Wood takes any paint colour or a stain: in our designer you can choose white, our standard colour, or name any paint or stain to match, including black.

Price

Vinyl is usually cheaper; The Shutter Store calls it “generally a more affordable option” than its wood ranges^[1]. Our shutters are wood only, priced as ranges you can see before you talk to anyone. A 36 × 48 in window in poplar with flat moulding and 3½ in louvers is $320 – $400 before tax and shipping. Prices for every size

When vinyl is the right choice

• A window inside a shower, or in the spray from one.
• A laundry or mud room window that gets wet hands and wet cleaning.
• A short-term rental where the cheapest durable option matters more than anything else.

Everywhere else, wood is the better shutter: easier to fit, any colour, and repaintable. If you need one vinyl shutter for a shower window, buy it, and put wood in the rest of the house.
