Quick Answer: The Wavestorm is Costco’s house-brand stand up paddle board — a solid, hard-foam SUP (not inflatable) built from an EPS foam core with triple marine-ply stringers, sold in 9’6” (250 lb capacity) and larger sizes rated to 275-300 lb depending on the specific model and source. Reported prices swing widely, from about $350 in-warehouse to $499.99-$599.99 online, per multiple independent owner reviews. It’s a genuinely durable, beginner-friendly board for flat-water paddling, but its rigid foam body means no rolling it up for storage or travel the way an inflatable board does — that tradeoff, not price, is the real decision point.

Every other brand covered on this site — iRocker, NIXY, Gili, Body Glove, FunWater — sells an inflatable SUP that rolls up into a backpack. Wavestorm is the exception: it’s Costco’s own house brand, and it’s a solid one-piece foam board, closer in construction to a soft-top beginner surfboard than to an air-filled SUP. That’s not a flaw, but it changes who this board actually makes sense for, and it’s the honest starting point for this review.

1. Wavestorm 9’6” — Best Overall

Wavestorm 9'6" Stand Up Paddle Board

Costco's most common Wavestorm size · about $350-$499.99
  • Solid EPS foam core with triple marine-ply stringers for rigidity, topped with a soft, textured foam deck pad — built more like a soft-top surfboard than a traditional hard SUP, per independent owner reviews.
  • Rated to about 250 lb, and reviewers note it's best suited to paddlers under roughly 250 lb given the foam-core construction's lower stiffness compared to fiberglass or inflatable drop-stitch boards.
  • Sold as a complete package: adjustable paddle, leash, and a padded carry bag included, matching the bundle most other budget brands on this site also include.
  • One owner reviewer paid $350 in-warehouse but noted the same model listed at $499.99 online months later — a real price swing worth checking before you buy, not a typo.

The 9’6” is the size most Wavestorm owner reviews actually cover, and the consensus is consistent: it’s stable, forgiving for total beginners, and durable enough that owners report jumping on it and banging it around without damage. The tradeoff shows up the moment you try to turn quickly or paddle in anything other than flat water — reviewers describe it as sluggish on sharp turns, which rules it out for surfing or fast-water use even though it handles open, calm-water paddling well. That’s a fair trade for a board this affordable, but it’s worth knowing before you buy expecting surf performance.

2. Wavestorm 10’6” — Best for Taller/Heavier Paddlers

Wavestorm 10'6" Stand Up Paddle Board

Larger Wavestorm size, higher capacity · about $499.99-$599.99
  • An extra foot of length over the 9'6" model, with capacity cited at 275-300 lb depending on the specific listing and source — a real inconsistency worth flagging rather than picking one number.
  • Same EPS foam-core-plus-marine-ply-stringer construction as the 9'6", so the added length trades a little maneuverability for more stability and a higher realistic weight ceiling.
  • Same paddle/leash/bag bundle included, and the same seasonal Costco-only availability pattern applies.

The 10’6” is the size to look for if you’re above the 9’6” model’s roughly 250 lb comfort range, or simply want more stability for two people taking turns rather than a dedicated tandem board. Independent capacity figures for this size aren’t fully consistent — some sources cite 275 lb, others up to 300 lb for what may be a slightly updated version of the same board — so treat 275 lb as the safer planning number rather than assuming the higher figure applies to the specific unit you’ll get. As with the 9’6”, this is a flat-water, beginner-to-intermediate board, not a performance or surf-specific shape.

Wavestorm by the numbers

Wavestorm vs. an inflatable board

This is the real decision, more than price or brand. A Wavestorm is a solid, one-piece foam board: no pump needed, ready to paddle straight off a roof rack, and reviewers consistently praise how much abuse it can take being “banged around” without damage. What it can’t do is roll up — it needs a roof rack or a large vehicle to transport, and dedicated wall or garage space to store, the same as any traditional hard SUP. An inflatable like the budget-tier Roc Explorer or a mid-range board from our paddle board brands roundup rolls into a duffel bag that fits in a closet or a car trunk, at the cost of a slightly softer, less rigid ride on the water. If you have a garage, driveway, or roof rack and want a nearly indestructible beginner board at a real budget price, the Wavestorm makes sense. If you’re paddling from an apartment, traveling by plane, or just don’t want a 9-foot object taking up permanent space, an inflatable is almost always the better fit — see our full inflatable vs. hard paddle board comparison for the complete breakdown.

How to choose your Wavestorm

The bottom line

Wavestorm is a genuinely different product from every other board on this site, and that’s the point worth understanding before you buy one: it’s Costco’s solid, hard-foam house brand, not an inflatable, and its real advantage is rough-use durability at a real-world price of $350-$599.99 depending on size and where you catch it. The 9’6” (about 250 lb capacity) is the size most owners actually have and recommend, and the 10’6” steps up capacity for taller or heavier paddlers. If you have somewhere to store and transport a rigid board, it’s a durable, beginner-friendly buy. If you don’t, an inflatable will serve you better regardless of price.
