Yes, you can just purchase the patio umbrella without having to buy a new set as long as the patio table has a whole cut out for an umbrella. I purchased my patio umbrella at Target.
I believe your local utility and garden shop can offer you table umbrella that can fit your patio. The price range of those umbrella is also flexible so that you can choose at the fix of your budget.
You can get a new patio umbrella table from Walmart, Sears, Home Depot, Lowes or your local hardware or lumber store. It just depends on what you want and how much you want to spend.
When you get an outdoor umbrella for a table, be sure to stabilize it to the table. A gust of wind can blow the umbrella away and it could break the umbrella to where you can't use it again. Don't leave the umbrella up if wind is in the forecast. Strong rope can be used to tie the umbrella to the table.
I do believe you can find a patio umbrella that doesn't attach to a table. A good place to start looking would be your local discount store like Walmart. Where you place a patio umbrella has more to do with the umbrella base or stand than it does the table. A table does help to stabilize the umbrella but it is not necessary. By getting a heavier umbrella stand or even a rolling umbrella stand you can place your outdoor umbrella any where you want to.
There are many places where you can buy a new umbrella stand for your patio table. I would check out your local Kmart or Walmart to find a cheap replacement so that you won't have to burn a hole in your wallet buying one online or at furniture stores.
Looking for Illy round table and umbrella
Umbrella stands outdoor decorations are pretty and functional. They hold an umbrella in place in the center of a table. Without a weighted stand, the wind can catch the umbrella and cause your table to flip over. If you have a glass or lightweight metal table, this can damage or break your table. Umbrellas should be properly secured into the stand to prevent damage.
The largest sized table that is available for an outdoor umbrella can handle up to ten chairs. It would be great for a large event.
Offset umbrellas are becoming more popular as they do not require a hole in the table for the umbrella to go through, and can easily be moved to accommodate movement in the sun's direction, or over sitting chairs. I would recommend a website like Amazon.com to search for the umbrella.
You are able to get table umbrellas in a variety of different shapes, colours and sizes. Your decision in which umbrella to get will have on impact on the price. Generally you will be able to buy a standard table umbrella in different colours from around $20-$50. However the price can rise to hundreds, depending on size, brand, etc.
Well you just have to measure the length and width of it. After you've done so visit The Home Depot for some help looking for the specific size that fits your patio table.
