And I’ve long been looking for the ideal pizza stone. This one is it. The size it amazing. Fits the entire oven. The weight and thickness hold the heat exceedingly well. I’ve got two of these now and I put one on each rack so I can bake four homemade pizzas at a time. Some tips; * Put the stone in before you heat the oven to 500-550 degrees. They need to heat up gradually and you need all that heat. * Preheat them for an hour. It does take that long to get them to retain all that heat exceedingly. * Don’t wash with soap. All you need to do is scrape them clean with a rubber or plastic scraper and then rinse with hot water. * Let it dry thoroughly before putting them away. Highly recommend. Review: Never used a stone before bought it to Keep my temperature stable in my oven to make macarons. Did lower the temperature slightly which was a bonus. Very disappointing there was a chip in the corner. As the stone will live in the oven I won’t notice as I can’t see it. Otherwise I’d give 5 stars. ## Features - Large 20" Oven Pizza Stone: 20" x 13.5", Golden 0.67" (17mm), Weighs about 12lbs, Bake 2-3 pizza or pan loaf baguettes at a time.

We have a 27" wall over with a 20" wide rack. I'd like to put this on lower rack but it only allows 19.75" item on top.** A: Mine measures 20”X13.5”. You should always place a pizza stone on the lower or middle rack of your oven. If placed on the top rack the moisture from cooking will render your dough soggy, not crisp. **Q: Can I cook things like biscuits, pigs in a blanket, and baked brie with puff pastry with the stone?** A: Yes, but since you typically want the stone in the oven while it's preheating and you are assembling the biscuits or pigs in the blanket ahead of time it's probably easier to put on a baking sheet. However, you can certainly just put these directly on the stone. The puff pastry or other products that are oozing fats will discolor the stone, but shouldn't hurt it. **Q: Can this stone be used over an open fire? Thanks** A: I would be cautious It requires a regulated temperature and I don’t believe that using it over an open flame such as a campfire or pit would no be able to regulate temperatures **Q: can it be cut with a concrete saw?** A: You could but why? You would expose the reinforcing fabric and who knows whats in that. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by S***B on November 29, 2025* We bake pizza every other weekend or so.

Did lower the temperature slightly which was a bonus. Very disappointing there was a chip in the corner. As the stone will live in the oven I won’t notice as I can’t see it. Otherwise I’d give 5 stars. ### ⭐⭐⭐⭐⭐ Review *by A***W on July 18, 2025* I broke my 14 inch round pizza stone recemty and needed to get a replacement. Was having a hard time finding a larger round one the same size, so decided to just get a larger rectangular one, also because I wanted to be able to bake more than 1 loaf of bread at a time too. This arrived fast and extremely well packaged. The stone was in perfect shape. I washed it and dried it in the oven. I keep it in the oven in the lowest rack when not needed. I find it helps keep the oven heat constant and even. So far I have baked a few baguettes, some sourdough and some pizzas on the stone and results are very good as long as the stone has been pre-heated enough. For me I find a minimum 40 minutes using the convection setting. 60 minutes without. Overall, very happy with this baking stone. ## Frequently Bought Together - Unicook Large Pizza Stone 20 Inch, Rectangular Baking Stone 20" x 13.5", Heavy Duty Cordierite Bread Pan for Oven Grill, Thermal Shock Resistant, Ideal for Baking Different Sizes of Pizzas or Bread - Saint Germain Bakery Premium Professional Bakers Extra Large Couche 35"x26" from France - Heavy Duty Proofing Cloth 100% Natural Flax Linen --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.uk/products/767744801-unicook-large-pizza-stone-20-rectangular-baking-stone-20-x](https://www.desertcart.co.uk/products/767744801-unicook-large-pizza-stone-20-rectangular-baking-stone-20-x) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-05-16*
