Would this be an ideal home for an adult iguana

I'm planning on getting an iguana.. but i want to start off with a big reptarium where it will be his permanent home. I was thinking if the new Exo-Terra Glass Terrarium would be too small. The biggest size they have at PetSmart is 18" x 18" x 24" (LxWxH). Then I was thinking of the Reptarium by Apogee. They measure their terariums by gallons. They have a 175 gallon it measure 29" x 29" x 48" (LxWxH). There is also a 260 gal. measures 29" x 29" x 72". I don't know what a good size home for an adult iguana would be. I actually am second thinking on the Apogee Reptarium because it is made of a kind of soft mesh kind of material, but it is said to help minimize odor and give the lizards fresh air. I'm quite new at this so I really don't know much about Iguana care. I have been studying quite a bit though, but you never know what the experiance will be like until you actually get one.

Adult Iguanas are just about 6 feet (72 inches) long from nose to tail tip. The largest cage you mention is less than 2 feet wide and long. You need a much larger cage. Look for at least 7 feet (84") long, wide and tall. Actually, larger would be better. He needs enough room so he can stretch out and not bang his tail on anything.

At least when he is adult size. It sounds like you only want to buy one cage for him, so these are not big enough.

They sell that soft mesh at hardware stores. You could make one yourself.
