Everyone's #1 question.
It would be easy to say, "results will vary" so I don't have to answer this question.
But I'm going to give you my best guess.
You can hold me to it IF you use your Bathmate at least 4-5 times a week for at least 12 minutes per session.
This is based on my experience and a TON of feedback from the Good Looking Loser Bathmate Forum.
As you might expect, there's several factors that need to be considered to give you an accurate prediction for what you can expect.
Other than 'how much you use the Bathmate' (how serious you are about gaining size), the primary factor is your PAST penis enhancement experience.
In general, there's 2 groups of guys -
You will fall in (or between) one of those categories.
As you might expect, this group of guys stands to gain the most.
They will also gain the fastest.
If you have never done PE before (or just done a limited amount), you will gain very quickly.
It is realistic to gain a 1/2 inch in about 2 or 4 months.
Even if you just use the Bathmate and don't do any other PE exercises.
As I've mentioned elsewhere, gaining your first inch is relatively easy. Especially your first 1/2 inch.
The second half of the first inch is a little harder to come by.
Newbies can realistically expect to gain a full inch in 6 to 10 months.
Some guys will take less time, some guys will take longer to gain their first full inch.
But 6 to 10 months (allowing up to a year) is realistic for newbies, in my opinion.
Doing manual exercises, using a high-end penis extender or losing weight will significantly speed this process up.
Either way, you can still gain a full inch in a year if you only use the Bathmate and don't do any other male enhancement work.
Again, this is just an estimate, there are always different cases and guys that have some prior gains before they use the Bathmate.
For example, lets say...
You have done PE, on and off through the years, and already gained about 1/2 inch.
You can expect Bathmate to get you to 1 inch fairly quickly. (3-6 months)
But once you have gained your first inch (in this case: .5" from prior PE, .5" from Bathmate), the second inch is tougher.
It might take an additional 6-12 months to get to 1.5" in length.
This was my experience (I had already gained .5-.75" from jelqing before I used Bathmate).
This group of guys has already gained an inch from doing various forms of male enhancement.
As you know, the second inch is harder to gain than the first.
For experienced guys and PE veterans who already have gained 1+", they can reasonably expect to gain .5" in 6 to 12 months of regular Bathmate use.
For guys that have already gained 1.5+" it will take 12+ months to gain .5" (for a total of 2"), if at all.
Naturally well-hung guys (7.5"+ naturally) can sometimes gain their second inch quicker than 12 months however since they have so much penile tissue to work with.
Bathmate, although largely a girth device, will certainly help you gain length.
If you have already gained an inch of length and are looking to gain more length, the Bathmate isn't the best option. Look into Sizegenetics or the Phallosan Forte, manual stretching or hanging exercises if you are strictly trying to improve length.
The amount of size you gain (and how quickly) really depends on which category of guys you fall into.
The gains that you make with the Bathmate depend on the rest of your PE routine as well as your previous PE experience -
The key is STAYING CONSISTENT.
The Bathmate is easy to use and you only need to wear it 4-5 times a week for 12+ minutes.
It's also quite fun to use and most guys have no problem with this whatsoever.
